The horrors of constant True Seeing...

[LazerPointer]

Corrupted landscapes?

Perhaps the ethereal version of some places absorb the energy of events that happen there?

On the upside, temples of pelor could be even nicer than they otherwise would be... Probably not so much fun hacking through the sacrifice room in one of Asmodeus holy places.

creepy places like a dark temple would fill the character with horror, all that tortured energy.

Seeing all the signs ACTUALLY saying things like, "Breed", "Consume", "Buy", "Stay Asleep", "Submit to Authority", etc. And lots and LOTS of Dopplegangers everywhere.

[For those who don't recognize this - see the really good/bad B-movie by John Carpenter, They Live!]

STOLEN! How could I forget about that cool movie *slaps forehead* Could even fully adapt that idea and introduce the "Goggles of Revelation" into the game
