Random Bit
It was realized, and prophesied long ago, that as a singular entity, it would consume and grow until all was gone into a wake of fire and death.
It was this reason, to prevent the prophecy from occurring, that it was divided. Scattered throughout the universe as shards of its former being. Shards that, eventually, would find hosts. Hosts that would influence the shards, and the shards would influence the hosts.
Unsurprisingly, being the herald of intergalactic, interdimensional, and frankly every-damn-thing else, a shard on Earth finding a host wasn't a surprise.
However, given the shards were largely unaware of each-others' existence, it would come as a surprise to the one carrying it.
