So, I was thinking about the Patji letter the other day, specifically the first few lines.
In the past, I had never really noticed the phrase "one who cannot respond". But seriously, what does that mean? Based on the first sentence I'm assuming Hoid originally attempted to reach out to Bavadin, but why wouldn't she be able to respond? The thing is, we always assume that Bavadin is this super powerful mastermind but... what if she's not? What if she's not in control at all?
Obviously there’s so much we don’t know about avatars, but my interpretation of them is that avatars are a way to increase a shard’s influence and awareness. The main limitation of shards is that while the shard itself is infinite, the vessel's mind, although greatly enhanced, is finite. But if you create avatars, more minds to help manage the power, it’ll greatly expand a shard’s consciousness. However that's super OP, and if this is the case, why wouldn’t all the shards be doing it? There has to be some sort of drawback. What if too many avatars can infringe on a vessel’s control? I'm thinking maybe Bavadin started creating avatars, and she slowly started losing her handle on Autonomy and it just spiraled out of control. (Also it's possible that wouldn't be the case for all shards, the nature of Autonomy might mean that these avatars have greater influence than other avatars would)
Specifically the quote from this WoB, "The avatars aren't necessarily aware but Bavadin always is" makes me think... imagine if she's alive but essentially trapped and unable to do anything, forced to watch in horror everything the avatars are doing. Alternatively she could be dead and the avatars have just been running the show for a while, unbeknownst to anyone else in the Cosmere. Also, maybe it wasn't Bavadin that locked up the Taldain Cognitive Realm, but her avatars essentially locking her up there.
I think this would be a really interesting (and really freaky) interpretation of Autonomy, let me know what you guys think!
