Lore

all the deities in Keifera serve some kind of role in making things

Lockhelm created mountains and caves and earthy stuff

Tantes created darkness and light and fire and things that could hurt you

and Yrntes created stars and water and things like that

Luma created life

and finally Keirogant bound it all together into Keifera and thats how everything came to be

'Fera' meaning the people (equivalent of humans) that live there and Kei coming from Keirogant

Keirogant is also Keifera's rings and sleeps there. in space.
