Yggrasil
 
Outside:
-The area outside Yggrasil is surrounded by thousands of Tarrying. Even to those without the power to see into the astral, dozens or hundreds of materialized ghosts seem to light up the night around its branches. Trains of pilgrims make their way to it every day by the hundreds, passing towards the next row of the Cycle.
 
Roots:
-The dead enter Yggrasil at its base, going under its roots into an airy underworld. This should be bright, pleasant, with greenery and running waterfalls and crystal, it should NOT be dreary. This leads to a spiraling staircare of a descending root. Upon this vertical assent they arrive in the Temple of Maveth, one of the holiest sites in the Fourfold Faith. Within all dead automatically Materialize, even if they lacked that ability. This is as far as the living are allowed, past this is the Gate of Foundations.
 
Gate of Foundations:
-Only the dead may pass through the Gate of Foundations into the trunk of Yggrasil. Immediately upon entry is the Lake of the Maiden. Passing through the waters feels to the dead as though warm milk [likely the first heat they've felt since death], though to the Tainted it feels like scalding metal, purging them of Taint. A phantasm of Ajax grips the unwilling and plunges them into the waters. Past the Lake is the Gate of Life. Phantoms of Kachina and Holly question the dead on their desires. Those who cling to Life cannot enter the Gate of Life, they pass into the Occult-Matrix and become Elementals.
 
Gate of Life:
-Ascending upwards higher into Yggrasil is all manner of plantlife, flowers of every kind imaginable form the Fields of the Spirited, with orchids of every life and shape. Here the dead feast and obtain sustenance, the first food since death, and feel their strength redouble. The Phantasms of General Chrome and Captain Diez, their feud ended in death, welcome the dead to feast with them before they pass to the Gate of Thought. Those who cling to Thought cannot enter the Gate of Thought, they pass into the Occult-Matrix and become Plants.
 
Gate of Thought:
-Passing through the Gate of Thought takes one outside of Yggrasil again. Due to a temporal distortion effect of the Gate of Thought, they always find themselves exiting at night. Under starlight the dead pass up through the branches on foot as weight and solidity is restored to them. Here they meet the Illuminated, Psyches who opt to stay here in Yggrasil meditating upon the borders of life and death. The Phantasm of Yushuna tempts the dead to depart from Yggrasil through gaps in the branches and resume Tarrying. A Phantasm of Monocera lives half-way through the branches, explaining the full nature of the Astral Plane, Psyches, and Astral Matter to the curious. Those who ascend further find Lord Surya's Phantasm sitting in meditation before the Gate of Law. Those who cling to the Law cannot enter the Gate of Law, they pass into the Occult-Matrix and become Animals.
 
Gate of Law:
-Passing through the Gate of Law is forbidden, as it leads to the Bridge of Knowledge. Passing onto the Bridge of Knowledge strips the dead of all the boons he has thus par obtained [feeling, sustenance, and weight] and reduces him to a ghost. Around him is a mystical void, in which appears the Phantasms of Law. By tradition first the Archer-Hero will appear before the aspiring Machine and fire arrows of fire at them. To those of conviction the arrows are harmless, and extinuish themselves on their Psyche. The Archer loudly announces 'Those who walk the Path of the Souless risk losing their souls, turn back!'. As they continue down the Bridge they are eventually accosted by the Phantasm of Amen-Hotep, who tempts the aspirant with necromancy. He promises alternate moral paths of Immortality, such as mummification or vampirism, and offers a seat in his Necropolis to the aspirant. If the Machine-to-be refuses, Amen-Hotep curses him saying 'Those who walk the Path of the Souless risk losing their souls, turn back!'. At the end of the Bridge stands the Gate of Immortality, and before it Mishna the Pious. The Phantasm tells the aspirant the dangers of being a Machine, how it is outside the plans of the Four, how it threatens the Cycle with unnatural immortality without risk or lessons. If the Machine can justify himself and his decision as being in accordance with the Faith, or declares his apostacy openly Mishna will either bless him 'Those who walk the Path of the Souless risk losing their souls. May you live forever.' or curse him, repeating the curse of the other Phantasms. Those who cannot attain to Immortality cannot enter the Gate of Immortality. They pass into the Occult-Matrix and become Machines.
 
The Occult-Matrix:
-The great machine Yggrasil has many logic-gates that filter the dead, but all eventually pass into its occultic computations, and find themselves before Yggrasil itself. Yggrasil answers any questions the dead has, explains the result of the path they have chosen [and offers a last chance to change their mind, unless they are Machines].
 
Notes:
-Might want to avoid Alexis experiencing any of the boons of the dead, to make her revival more significant.
-870,000 Tetrans die yearly
