The Elemental Shard

We seem to have some numerical trends seen across the cosmere, is there a reason for this, and how will this be incorporated in the future?

If so does the well of ascension fit this?

So I was thinking about the realmatic theory of how hoid's powers work. My theory is that somehow, he combines sand mastery with allomancy, the resonance creating an ability to connect you to hoid's story. This is (kind of) supported by Hoid's explanation of how he got his powers in Warbreaker as “ “I learned it many, many years ago from a man who didn’t know who he was, your majesty. It was a distant place where two lands meet and gods have died.” This possibly could refer to the well of ascension and his encounter with Kelsier in secret history.

Are trellism and the purelaker religion the same concept, changed because of the differences in time and space?There are some parallels between the religions such as the two brothers, and pretending to worship one, when they are really worshipping the other.

What is investiture? Where does it come from? Why does it exist?

ok this is gonna sound insane, but I think the big twist of the cosmere is that there are beings similar or even above adonalsium, or even adonalsium was just one aspect of a larger god. If you think about it, it does follow the theme of Gods above Gods that you find in the cosmere. Edit: I have actually found more concrete evidence while looking at the coppermind. There is a mention of the "God beyond" , mentioned by different characters over multiple shardworlds.
