Any God Figure/original Being In Wynncraft?

Also the gods of thunder and air from the Gemini lore

 

In the quest Temple of Legends, the dude Rayshyroth on Mage island says this: "The beast now known as the Corrupter of Worlds used to be a simple mining captain, during the expeditions that uncovered the Nether Portal. He was the first to enter that wicked realm."
I see what you mean with his name being Corrupter of Worlds though, it does sound like a big deal. Maybe we'll see more quests detailing the Corruption sieges in the Great Bridge/Troms to give him more background information.

 

Charon is kind of a god in Greek mythology, not sure.

Death is considered a god in many mythologies and religions, but I don't know if anything even addressees Death in game (well no one is supposed to remember their journey to Death's office anyway)

Qira calls you "mortal", so she must be some sort of... immortal? You don't go around calling random creatures "mortals" if you are mortal. Though she is more of a demon than a god.

Hephaestus is a dwarven god in the lore of Hephaestus-Forged Greaves, and is another god in Greek mythology

The two dudes in the lore of Gemini are gods who decided to turn themselves into a pair of pants

Gaea/Gaia is the goddess of Earth

Ra (bracelet) is named after Egyptian sun god

 

The guys in the kander cathedral also worship some gods, but I'm not sure if EotS is a good source.

 

There are some powerful beings being warships
There are some churches
But afaik there is no creator god

 

Charon isn't really a god, he was the guy that would take you across the river Styx if you died, to reach the afterlife. Hence the dagger Styx' Grab which you can get from the dungeon and the boat section, which figuratively takes you across the Styx.

Also I'm kinda confused as to why Qira calls you mortal because you're basically immortal.
