God of fire: Ignis [CN]
Portfolio: Rage & destruction
Ignis is fire and fire is Ignis. His emotions are projected in the way fire acts. Rage and destruction is the nature of the flame. Ignis is not an evil god. He does not wish to destroy the world or anything, but it is his nature to destroy, so if you invoke the flame it is what you get. If you worship Ignis you worship fire and flame.
