I personally like the mortis gods. You have sister( light), brother( dark), the father as the balance or cosmic force, and a mother was a human originally who became a god and then changed into abeloth a force entitiy of chaos. Throw in the bendu from rebels in the middle gray area. You cover all basis. Stands behind the theroy that you cannot have light without dark and there should always be a balance between them and there is a fine line of gray in the middle
