Aukan

Born in the Old World, this towering goliath stands tall even amongst The Old Ones and is the god of lightning.

After Jealousy ascended him to a demigod hoping to defeat him in battle, thereby regaining the honour he felt stolen from him due to being freed by mere mortals, Aukan is in a constant state of battle with Jealousy, causing lightning and thunder, and explaining why both of them strike seemingly randomly.
