Pre-History

Ancient Druids
	Ancient druidic magic is actually a mix of spirit magic and kinesis, which is a bit of a freak occurrence.  In-setting it is just considered to be like grandpa's inefficient spirit magic.  It was enough to make variants of elemental creatures exist where there were none, and this was part of how contract type spells could be formed by modern druids.  Anyway, mass-delusion aside, ancient magic needed you to provide all real world power via your own energy (they found it sufficient to just fuel magic with feasting, so it is close enough to say it's calorie magic).
	Culinary arts should be advanced despite lack of cultural exchange.  The ancient druids form the early foundations of mainland society and they had fairly advanced cuisine, though it necessarily trended towards calorie density, and so many of their recipes were discarded due to a lack of calorie magic.  Suffice to say that waste meats like chicken wings and sausage exist, as well as:  hard candy, stiry fry, deep frying, and various methods of food processing and preservation.  However, nutrition is not understood well, which has left modern cuisine in an awkward position despite the advanced techniques.  Ice cream might have existed, but magic reliance has dwindled to where dairy is functionally limited to cheese and butter.  Obviously, any traveling or novelty-focused food vendor will have a mage on staff (and would relish druidic knowledge).
	A lack of precision instruments demands an oral tradition held up by individual interests and local demands.  So even a willing druid could not simply write down one of their recipes - it requires tuteladge to pass on.  This also aids in slowing the industrial process.  So brand recognition can be valued, at least as much as can be understood - typically it will suffice to say "product from [citystate name]".  Yet another detail to be ignored in the videogame.
	The ancient druids had some remarkable architecture due to their magic (and unlike soul steel, communal editing priviledge).  This is rare knowledge, though, because all remaining constructions are lost to monster habitation (this has led to false theories of intelligence for various monsters).  Normally, all structures a druid group is discarding will be demolished and reverted to how they found it as best as they could manage.  This was out of a cultural respect for nature, yet they only take it as far as their own group is responsible.  Otherwise the current druids would be demolishing every settlement they find.
	The main cause of not cleaning up is imminent danger or an epidemic that kills them all.  A secondary measure could also be to hide the settlement or bury it.  So there are likely a few empty druid ruins beneath the surface.  These would be distinguished from other forms of ruin by a lack of tools, as they used magic a lot.  They would also have an abnormal amount of space dedicated to food storage and an occasional pile of rare minerals that were treated as baubles.
	Mundane traversal of large or intentionally subterranean constructions is frustrating.  Ancient druids had no need for stairs or doors.  One might mistake them as natural caves.  Navigational games were common, frequently involving the fundamentals of spirit magic:  sensing via spirit, deconstruction of matter, and reconstructing to original state.  Adults would pursue the finer skill of spirit negotiation - creating new techniques of applied magic.  Evidence of this can be seen with any strange, functionless sculptures - things like crystal lattices or fractal mirror chambers.
	Keep in mind they were generally naked and high every day.  This sounds like a joke, but it isn't.  There was little need for clothing with how easily they could control the world around them.  They didn't pursue drugs out of recreation initially - they were just eating everything they could chew to find more calorie options.  Naturally they ended up learning some basic medicine.  The actual field of medicine was not great, but efforts were torn on scientific progress and magic advancement.  Like I said earlier, there were few precision tools despite the means to create them, so in the end magic won all developmental effort.  This effort is what led to the modern druid magic school, as the old magic made "simple" cure spells a big ordeal.
