Why is a star making dragon god fighting....

Whatever he is fighting I don't think it is as important as why he is fighting. With aspect of death fighting on equal terms with a hamster with darts i think it is safe to say something weird is going on. What is the Rift? As far as we can tell it is a place where mortals, elementals, aspects of nature and gods fight to the death. I think that is the key; the reason why gods, monsters, men, and hamsters fight is because The Rift has the power to make all those being equal. Think about the power of such a location that it could weaken a god to such extent that a drunkard throwing kegs of beer could kill them. That power is literally unlimited and even more powerful then gods. A being could take an aspect of reality like death and kill it here! You can literally change the rules of reality by controlling the Rift. If a god is fighting another god they would certainly want this power. The problem is that any mortal with a knack for fighting could kill them while they try to take it. This is why A Star Forging, Sun crushing, super dragon god has come to the rift. Aurelion Sol wants to change something, some rule of reality or who knows what.
