So I've been wondering, we know that Adonalsium was shattered into shards, and we know that those shards can be further splintered down. I'm curious, is Adonalsium itself a 'slice' of something bigger that was in itself broken across the universe, with Adonalsium investing itself into the cosmere star system?
If so, would the "god beyond" actually be another 'slice' of the bigger thing which would have invested a different star system with a different investiture system?
