I'm working on a theory that may have already been discussed and dealt with, but with the discussions had between the dying preservation and Kelsier in the cognitive realm, there are sixteen shards, and sixteen metals, two of whom are clearly named for the holders of the shards. Wouldn't it make sense that a name that predates pretty much every culture would be represented intercosmerically by the shard's holder? Specifically. Ralcolest or Alumin, a shard of silence or weakness or non-investiture perhapse? It's been mentioned in MANY of his books as a remover of investiture. Perhaps this is a clue to the most dangerous shard. The one that eliminates all power perhaps. Just a running theory.
