Xom Temple in Pandemonium
So if you worship TSO then angels and TSO Fortress mobs will still attack you. So add a little lore in..! If you are near max piety with a holy god then Pandemonium has a chance to generate a Xom vault with four confused angels in a poison cloud. If you worship TSO then the first time a confused angel hits or kills another angel it sets off an easter egg voiceline. And through a combination of Xom's pressure plate, mephitic cloud, angels attacking each other in confusion, and TSO placing angels under penance, all of Pandemonium ended up being under penance because of the faithful angels entering penance when they attacked the penance angels. And TSO comments on this. This would explain why holy mobs attack worshippers of TSO/Ely/Zin.
