If you truly dont know who Sithis is i'll fill you in.

He is basically the void: a lack of existence, he is darkness within itself and represents a time before even the aedra and daedra were formed

so his is the realm before time, space, dragonborns all that

I suppose he could be the king of everything i mean he was here literally before EVERYTHING
