Thymos
When the primordial gods Akalana and Eon sang, their songs became the gods of our pantheon. Some were songs of love, others devotion. But when chaos took their first child Proros, Akalana began to wail–her song of rage taking the form of Thymos–God of strength, wrath, and vengeance.
To this day in war and violence across the Thalassos the followers of Thymos embody that first wicked rage.
