His soldiers went from divine kingdom to divine kingdom killing and pillaging. The pillaging didn't stop until every god had died. Even the divine city was looted. He took the bulk of the wealth while his dukes and their subordinates helped themselves to what was left. And that's only because it wasn't worth the effort to take them himself.
There was so much wealth that the looting took a few days before it was completed. It is wealth that would have made Ancestor Ghastorix whistle in admiration. If he had this, then he wouldn't have had to sell out his descendant for a world engine.
Origin gods are wealthy but it costs a lot to resurrect the more powerful they are. They fight a lot and they die a lot which drains their resources. Getting more resources also won't happen without fighting which will further lead to more deaths. So rarely does an Origin god come into contact with this kind of wealth.
