So what about the Adonalsium sentients, are they partitioned into Shardic alegiences, or do they have a little of each shard? Maybe this is why the personality of the shard gets skewed towards the intent, because most humans only have a little of a shard in them, the larger the part the more skewed you become. (stating the obvious). Maybe this is why Hoid and the 'original' 17th are doing things: Their sentience is split over lots of places, and is probably balanced over each of the different shards, ultimately wishes to be unified once again, over the goals of the individual shards.
