Cosmere - Shards and Magic
Are the magic systems tied to the world or to the Shard? For example, if Ruin and Preservation had landed on Sel instead of Scadrial, would Sel have Allomancy, AonDor, or a third unrealized system? Also, do Shards bring "their" magic with them? I'm thinking specifically if a moving Shard like Odium is leaving a trail of magic systems behind him.
