The island

The island is a volcanic island situated in south western Europe. It has a Mediterranean climate, and is in the Atlantic, West of Gibraltar, approximately 900km away from the coast.
It is around 10km² in size. Half of the usable land is occupied by the palace.
Yachts typically are found idling around in the nearby waters as most cultists are extremely rich and come either from yachts or by plane/helicopter.
Of the remaining land, half is occupied by vineyards and fruit gardens. The rest includes a few plains, lots of forests typical for that climate (Oaks, dry pines, shrubs). The sound of cicadas is permanent.
The volcano, mount Gigas, is dead. The caldera is full of water. The insides of the volcano, around the caldera, have been carved into, corridors and pillars sculpted into the rock – it is possible that there is a temple in the volcano, and many passages from and to the palace.
Caves are common, and a natural cave network can be found under the island. Underground rivers are also found. The caves have been decorated, dug further, etc in places.

Palace

The palace is built around a fortress from the 600s – probably built by the Spanish, taken over by Umayyad caliphate for a while, which added a few Arab parts to the already existing European parts of the fort. It probably was taken over again by either the Portuguese or the Spanish later.
Other structures include a few ruins, some farms and houses, a dock, and a concrete landing strip and heliport (Concrete required for personal jet landings). The heliport is useful for people taking the helicopter from their yachts to the island, and a few members of the cult can fulfill the functions related to landing operations and ground control. Same for the docks, although most of the work will be done by slaves. Slaves having been there since their childhood, none is able to pilot, and they are generally trusted around aircrafts if cleaning tasks, for instance, are required. They are much less trusted around boats.
Most of the palace is more modern. It is very luxurious. Marble floors, marble pillars, ornated and decorated walls, doors, and corridors. The roofs have red ceramic tiles. Many small gardens are embedded inside the palace, directly under the sky – there are typically pools and fountains with mosaics, palm trees and other plants, statues. 
Technology is relatively rare in most places but not all. The administration and entries area for instance has to contain means of communications to the outside world – the cultists are very busy and a CEO with lots of free time is completely unheard of. Furthermore, the island must be able to contact patrons that are outside, for instance to arrange their next visit and show them available “toys”. In the same way, they may call the island, make demands, and such, in advance.
Payments also need to be processed. 
This means that a wide array of computers, servers, means of communications etc are available close to the port and airstrip – a few persons are always present. Slaves are rarely allowed there however, aside from the entries department where they are stripped of everything, given a name, branded, and recorded – a picture is taken of them, which is of course good to show to cultists who plan on taking a vacation soon and want an appointment with some of the … personnel. 
A typical scenario would be a red cultist phoning in the administration service, asking to see a certain range of products – giving age ranges, sex preferences, and such. They can browse the available slaves, pick one, decide an appointment, book a room or more – IE, a dungeon.
Some are overbooked, and plan for a quick fuck. They come to the island, are quickly given directions, do their business and leave to return to their busy life. Some plan entire vacations, and stay in their room for a little while, profiting from whatever attractions the palace has to offer in the meantime, grabbing slaves at random.
Logistics are mainly assured by boat. Slaves that are thought not to want to escape oversee hauling things from and to the boat, under tight supervision. This must be done under 30 minutes as the same boat supplies other islands in the area. The company in charge of the logistics is owned by the cult, and therefore no random, unknowing employee would see anything wrong with the slave labor at the docks.
The imports are largely food, cleaning products, and other consumables but they also contain specific ordered luxuries. The exports are mostly resulting of slave labor, such as very fine alcohol and other things – since the island is essentially an international grey area, they can get away from selling things that would be perceived as strange elsewhere. It is quite possible that odd sculptures made of unique bones, decorated with jewels, are sold as well. These bones do seem to come from slaves.
If a special delivery must be made quickly, a jet can be ordered.
The red quarters can be accessed by anyone, anytime. They are a set of luxury rooms, gardens, dining halls, lounges, baths, pools, dungeons. The slave quarters are directly accessible from them and slaves are commonly roaming this area, where they can be grabbed at random. The slave quarters themselves are a dormitory, without windows, with bunk beds, no covers. The slave sanitorium, nearby, is a very long set of old sinks. The showers are of course common. Slaves that are too young to clean themselves are to be cleaned by other slaves. Diapers are available.
Slave quarters resemble more a middle ages asylum and monastery than anything modern and luxurious.
A lot of the tables are heavy, long dining tables made from marble. The chairs are also stone thrones. Slaves always work on food production, and there is always food on the tables, with no real set hour for eating – food is regularly cycling, replaced, refilled. There are lavish alcohol fountains. Purple is a common theme, purple banners being displayed everywhere, along as luxurious purple carpets outlined with gold.
The lounges are very comfortable, with fireplaces, velvet sofas and other cushions, small tables are there to take drink from. The floor is generally oak, and so is the furniture. It is generally expected to have servants at disposal in the lounges, and preferably one of them on whatever instrument may be in the room – generally a harp.
The rooms themselves are luxury rooms, with a bathroom and all the hotel service you would generally expect, though there is no Wi-Fi (which, anyway, isn’t relevant as one is rarely allowed any form of communication technology inside the palace), and no TV. 
A lot of these rooms are general luxury rooms. However, Residents who permanently own one of these may decide to change it entirely to fit their … needs.
As such, specific examples may include:
-	Extravagant rooms designed by insane people, with furniture on the ceiling and such
-	Rooms with a fireplace, a mead fountain, everything made from wood and furs replacing the bed on the ground
-	A fighting ring. It could be for someone to beat up a child slave, or have slaves beat each other as a spectacle
-	A torture dungeon.
-	A full ABDL nursery (Note: not all cultists are dominant. Although a cultist will generally not get dominated in public by etiquette, they may very well have intercourse with other cultists – they do have rights however and cannot be raped, for instance. It is not impossible to have a cultist be a grown ABDL, asking slaves to take care of him… or other cultists)
-	Watersports or scat related room, made to be cleaned easily
-	Rooms from another time era.
-	Rooms filled with inflatable things
-	Rooms to fit the incorporation of feral animals. Cages, accessories, kennels, breeding stalls
-	Gym rooms, for muscle addicts – though gyms are of course present in the palace.
-	Much more.
Most people will generally be fine with a normal room, as they just want a luxurious place to rape someone, or have fun with their fetishes – paw fetishists for instance generally don’t really feel the need to get more than a regular room. 
A single gate leads to the white quarters. Much more luxurious, fully golden in places, doors are much more spaced – this is because multiple luxurious apartments are to be found for each member. Red masks cannot enter, unless invited. Only the white cast and above have the key for the main gate, although many known and unknown secret passages may make the task more difficult.
There is no real difference otherwise – most white masks will go to the red masks zone in order to use the same lounges, dining halls, baths and such. Otherwise they tend to take slaves into their own quarters, behind the white gate.

What the white quarters do have that the red masks do not, is a few administrative services, but also decision councils, and a chapel. What is done in the chapel tends to be secret but not all white masks participate in it. It is generally calmer and less slaves are seen out and about – only the ones who have been instructed to be there, whom are generally the same. A white mask must open the door for them. 
Another thing that is present is the guard’s barracks – guard slaves sleep in dormitories, also have common showers and sinks, but these are of better quality. They also have a proper dining hall and are properly fed as they are expected to perform accordingly. 
The barracks are a monastery. They train in the court, all day long, when they are not on guard duty. Rotations are made. New guards and enlists are NOT trained in these barracks – only actual guards. New chosen guards and guards that undergo their intense basic training are in a specific, walled in monastery that is out of the palace. Less than half make it to the final graduation. All that do are tough enough not to need the ones that died – sometimes, possibly, by their hand as they were put up against each other.
The purple gate is further away, in the main corridor. It requires the purple key.  The corridor is magnificent and giant statues are on the sides – but also, a few guard slaves are permanently guarding the door. 
It is believed that there might be passages that lead past this gate – but these are all unknown since the cult really does not want them to exist, allegedly.
The purple quarters are a mystery. Most doors are closed. Slaves are almost never seen. Neither are purple cult members. The corridors are the size of avenues. Harp melodies, sometimes flute and violin, seem to be playing in the distance but the musicians are never seen. When purple cultists are seen, they are generally wearing a mask and a robe with a hood.
None seem to be living there – they generally own an entire mansion somewhere on the island. There are crypts, catacombs, giant arches, and bridges surrounded by massive golden statues that seem to be made after people that existed but are not named. In some aisles, choruses can be heard, sometimes screams. Colored windows, like in a cathedral, always illuminate statues and altars. A giant statue towers everything else in the central cathedral. It represents a massive wolf with two penises and 4 pairs of eyes, as well as 3 arms. Due to the mechanisms, it rotates in such a way that it is always facing away from the sunbeams as it is surrounded in multiple colored windows. At the base level, giant gates are found – only the one in the shadow of the tower will open. It leads into a labyrinth, which itself leads to the quarters of the cult leader. These are a palace in themselves and it is supposed that he has his own slaves there, as very few ever enter, and fewer ever come back. 

Vineyards, mansions, farms

A few fields are available.
They include:
-	Olive trees
-	Orange trees
-	Apple trees
-	Vineyards
-	Lavender fields.
The olive trees are regularly harvested for olives.
The orange trees are harvested for oranges. Some of these oranges will be used for alcohol.
Apple trees are harvested for apples; some cider will be made.
Vineyards are harvested for their grapes. A lot of them will be processed into wine.
Lavender is for the honeybees, which make honey – slaves harvesting the hives. They also harvest the lavender itself for perfumes.
Slaves sometimes die as they perform these tasks, mostly hive splitting, as they are often cubs and wear no protection.
The farm building is mostly handled with little technology under the surveillance of quartermasters.
The mansions are guarded by guards. They are surrounded by swimming pools, courts, gardens, statues. The mansions themselves are huge. They belong to purple cast members. 
Mausoleums are found across the landscape as well. Temples are not too far, though they are guarded and very well closed. Peafowls are found across the island countryside.
