This level is a change from the earlier levels of the dungeon – instead of a mix of creatures and dungeon denizens trying to get along, this is an evil temple with a surface exit, acolytes and clergy.
The surface exit is important, in my opinion, when building a megadungeon. It allows the adventurers to skip the earlier levels when re-entering the dungeon in the future.
To give the level some character, in addition to the Acolytes, Mediums and Veterans I’ve been using to represent the temple staff on the upper levels, I’ve added a unique member of the clergy, as well as a room with visiting representatives of a powerful creature who lives much lower in the dungeon.
