First time posting here,
I thought I remembered a WoB about Ashyn having a shard of Self-contradiction, when talking about The Silence Divine. I was unable to find it, but I did find this.
If a Shard ruled Talents (Alcatraz), what would the Shard be? Betrayal, or inner self-contradiction, people contradicting themselves in some way.
That is not proof of such a shard, but it is highly suggestive.
Then there is that something Hoid said, about spending a year being digested. I don't know about any shard that could correspond to. Perhaps, there is a shard of Consumption, or Hunger?
I do like the idea of Honor+Odium = Justice
That would be a great end to the Stormlight Archive.
