Hoid and the 17th shard

[Straw]

Due to it's name a believe that the seventeenth shard was founded by Hoid and was allied with Hoid before odium started killing shards. Here are my reasons:

A. Hoid was there at the shattering and thus if there had been another shard he would have taken it thus becoming the 17th shard.

B. Hoid seems to have a abnormally good knowledge of the 17th shard and vice versa.

C. Hoid knows the leader of the 17th shard.

D. Hoid has knowledge about the workings of the cosmere thus making him a perfect fit for a job involving shards and the cosmere.

I think Hoid and the 17th shard parted ways because of odium killing other shardholders which the 17th shard saw as a thing irrelevant to the state of the people of the cosmere but Hoid saw it as a direct threat to the people of the cosmere thus causing the two parties to part ways.

I am being chased. Your friends of the Seventeenth Shard, I suspect. I believe they're still lost, following a false trail I left for them. They'll be happier that way. I doubt they have any inkling what to do with me should they actually catch me. If anything I have said makes a glimmer of sense to you, I trust that you'll call them off. Or maybe you could astound me and ask them to do something productive for once.

 

This quote from the Letter written by Hoid is what makes me think that he is unaffiliated with them. The fact that they wouldn't have "any inkling" of what to do with Hoid, presumably to kill or incarcerate him, makes me that that the organization does not have much information on Hoid, I would think they would know more about their founder and former leader, though this could just be because Hoid always seems to obfuscate the truth with his jokes and his deflections or because Hoid is just that difficult to hold on to, enough that people who know him intimately still can not stop him. 

 

Hoid also mentions that the 17th Shard might do something productive "for once," which to me implies that Hoid has believed this organization to always be useless, so I doubt that this was a group he was at one point leading.

 

I don't know. There's not enough evidence right now to prove or disprove this theory, but your B and C points are true for many things; Hoid seems to have abnormally extensive knowledge about most Cosmere-tier entities and organizations, and also personally knows many if not most of the major players in the Cosmere, and I think we can assume the current leader of the 17th Shard fits into this category.

 

Your D point about him being qualified for the job would probably also be true to a certain extent for other Worldhopping organizations, such as the Ghostbloods, whatever Khriss is doing, or (Mistborn: Secret History Spoilers)
