the greek mythos has alot of gods. but for to sake on simplicity I’m going to focus on the major gods, these are the ones that grant spells to clerics, favored souls, and paladins.
King of the gods, lord of the sky, thrower of lightning, slayer of Typhus the calamity. Zeus is the most powerful of the gods and their ruler. he is married to Hera the goddess of marriage. all major cities give sacrifice to Zeus as the king of all, same with his brothers Poseidon and Hades. His domains are, air, lordship, community, human, and elves. more ot be added as needed.
Lord of the seas and master of natural disasters. Poseidon rules all the oceans of the world and protects them from the remaining titan beasts. He is worshiped at every major city, and any village where fishing or ocean travel is important.
