Dungeon ruleset governing deity temples that made Vinata's trap legal and Carl's team the trespassers.
The Announcer declared temple rules and floor rules both in effect for the Super Heavyweight Temple Battle Grudge Match Extravaganza, and added that deity summoning doesn't count against your limits when temples are involved. Khepri's own listing spelled out the consequences: the god is within his own temple, so temple appearance rules apply, and as a deity he is invulnerable on this floor.
This is the entire mechanism of Princess Vinata's trap — she worshiped Khepri, arranged to summon him into his own temple, and waited, so that Carl's team would enter as trespassers into a god's home. When Admiral Corinne Whimpleshin tried to call a Foul on the summoning, Baroness Victory shut her down: it doesn't matter, they have no standing, temple rules apply, and Corinne knows that.
The rules framework that makes a god's temple a legally sanctioned killing floor for intruders.
