The pharaoh of Osirion rarely leaves the Dome, the carapace of an enormous beetle - "I guess while we're sharing all our terrifying secrets I should mention that it's not actually the carcass of the beetle, as widely understood; it shed this carapace when it got too big for it. It's sealed beneath the earth. We just hope it keeps."
The beetle prevents scrying, teleportation, divination magics, and communications across its walls; the inside also has lots of other magics on it, meant to make it difficult for casters not authorized and trained by Osirion to operate; they should plan on mostly not using magic. The guards will require them to confirm under a Truth Spell their peaceful intent towards the pharaoh and everyone in the Dome and their understanding that the use of magic for combat is not permitted even in self-defense.
The pharaoh is a god, and visitors prostrate themselves when they see him; they may not look at him, or sit up, or speak to him, without his permission. If they try to stab the pharaoh or do unidentifiable magic in his presence they will almost definitely be murdered about it.
Hagan looks so unhappy.
