Sapient Orb

These enigmatic, orb-shaped beings seem to have no home world, organized society, traditions, or religion. Sightings of the orbs are sporadic—they briefly appear in large numbers, then vanish for a year or more, only to reappear in an entirely different region of space for a few months. Scholars and friends of the orbs have noticed that each time the orbs appear, their numbers have diminished.

Sapient orbs occasionally form permanent bonds, merging three to six orbs (always of the same type, as far as anyone knows) into a cluster called a luminant. Only sapient orbs at advanced stages of their life cycle can form such clusters, and the merge is permanent and irrevocable. Luminants are highly intelligent but far more reclusive than other sapient orbs, making it difficult to discern their motivations or purpose in sapient orb society.
