That's a really interesting question, and it brings up another one. How did each Vessel decide which one to take? I don't know if I could devote millennia to a single Intent. As we've seen in the books, holding a Shard takes a toll on the Vessels. In Secret History, we can really see how far gone Preservation was by the end of his life. Honor was in a similar state near the end of his life, and we haven't even seen very much of that point in Roshar's history. It's been shown that when someone holds a Shard, it slowly consumes them until the Intent takes control. I'm curious to see how Sazed handles both Ruin and Preservation. It's been hinted that sometime in the future of Mistborn, Harmony will turn to Discord as Sazed faces the internal struggle of holding two shards with seemingly opposite Intents.
I guess this is just a long way of saying I don't know which Shard I would want, and that I probably wouldn't want to take any of them.
I have been a lurker of the various Sanderson-themed subreddits. Unfortunately for me and my fellow introverts, there isn't much here to lurk at (yet!). I thought maybe we could get things started by discussing how we all got into the Cosmere. I'll go first!
In November of last year, a friend of mine recommended I read Mistborn. I had just barely started reading again after a long break and was in need of a new series. I was about to go on a long drive, so I borrowed the audiobook from the library so I had something to listen to. I didn't realize what I was getting myself into. In the last six months, I have read every single Cosmere book I could get my hands on, and have absolutely loved each one. I finished it all off with Tress last month. My only regret is not getting into this sooner so I could have been a part of the Secret Project Kickstarter.
Here's hoping we can get this community going!
