Emergency procedures Katia invokes as a cover story; the mantaurs have no idea what they are.
According to Tipid, Temple Defense Protocols is the name of the temple emergency procedures — the phrase Katia shouts while disguised as a gore-covered mantaur claiming demons are attacking the Temple of The Dagda behind her.
It lands badly. Everyone stops, and Joey — one claw still stuck in the ceiling — simply asks what temple defense protocols are. Carl notes that such procedures change from season to season and sometimes go away entirely, though it's equally possible this particular mantaur is just an idiot. Katia recovers by improvising: fight to the death, kill all heathens, the demons are coming, steel and heavy metal.
The bluff at the heart of Katia's decoy, and the moment it nearly falls apart.
