Behind the Scenes (BtS): Crystal Pylon (Patreon)

You might recall one of the earliest points of interest, aka. mini locations, in the UVG: the Crystal Pylon. Or you might not, it's pretty forgetable:

" 

Crystal Pylon (+2 days, 150 XP): a voluptuously whorled crystal pylon lies on its side in a heavily eroded crater, the sides covered in a riot of perfumed mind-altering brambles. Nomads say it transforms memories into life. This is true (touch with forehead, lose 1 point of Intelligence permanently, gain 1 hp permanently). Ultra possessor at night, millipede mechs during the day. 

"

Well, I'm expanding it to introduce a little bit more of an encounter. Once cleaned up, it'll never be much more than a flow chart, but I think it should be a fun conceit - traveling through the ruined memory palace of a Long Ago higher civilization called the Viles by expending Wisdom to consciously travel between rooms.

Foolish PCs will wander around and die. Smart ones will realize that if they move between rooms unconscious, they lose no Wisdom. So ... they might take turns knocking each other unconscious, blanking their minds, casting Sleep or some other such effect.
