Is the Power Creating Avatars a Function of the Power?

The power itself would be fracturing in this way, regardless. That makes me think that it is a function of the power and not something that the vessel Bovidin is necessarily choosing to do. She's just like nicking a shard, nicking here and there, and just leaving and waiting for tremendous amounts of time. I think Odeum is very clearly trying to destroy shards to be the only one remaining.
