ToME: the Tales of Maj'Eyal

Not sure what's going on, but the non-aggressive sandworms appear to be ginormous. The tunnels they dig are also ginormous, and there seems to be weird pathfinding pertaining to moving around them.

Image here.

Oh, extra weird - at the next level, they reverted to normal.

you hit alternative lair.

alternatives i know
old forest - has 1 massive castle taking most of the first lvl (or maybe that's just a vault...)
old forest - corrupted by the crystals
lake of nur - last lvl might be under water
trolmire - swampy
dikara - volcano eruption
rhaloren camp - first 2 lvls are on the surface
scintilating caves - layout change, 5lvls
norgos lair - blizard ice elementals (shigoroth?). boss is frozzen and immobile
maze - ruined and corrupted. minotaur at the end is now an eldritch horror.
sandworm lair - first lvl is long and thin. you follow a single worm digger to the end.
korpul - taken over by bandits
heart of the gloom - turned psychic


might have missed 1 or 2.

Ah! Neat. Ok, thanks!
