I have a feeling that Hoid may be trying to resurrect Adonalsium. It has been implied that he believes the Shattering was a mistake. Additionally, he seems to be gathering Investiture from each of the Shards. In a way, he is reuniting pieces of Adonalsium. It has also been strongly hinted that at some point, more Shards will recombine, a process that likely started with Harmony, though I have a theory that Odium has been doing something along those lines. Considering how powerful Odium seems to be, even among the other Shards, and that only Harmony's power is close to rivalling him, I believe that Odium has not truly been completely destroying other Shards. I think he is stealing the power of other Shards for himself. My theory there is that at some point, Hoid, Harmony, and characters from every planet, will face off against Odium. This makes it likely that Hoid is preparing people on each of the planets, and is trying to gather a force that can counter Odium.
