Godless big naga commanding the castle guard, the Sultana's real-life boyfriend, killed hard by Elle.
Pushing toward The Throne Room, Elle runs into nagas and NPC guards who all worship Emberus — except one. The big naga worshipped no god at all, and he went down hard, taking far more killing than the rest.
Katia receives the death notification and concludes he must have been the head of the Naga Castle Guard and one of the four required kills. Carl adds the detail that makes it worse for the enemy: the dead naga was also The Sultana's real-life boyfriend. Good, he says — she'll be extra upset, and hopefully she'll start making mistakes.
A big naga, notably larger and tougher than the ordinary castle guards, and the only one among them who worshipped no god.
