Little is known of the Delirii other than tales handed down over time. They have long gone from this area of the universe, and only the relics they built on our planets leave any proof that they existed at all.
What we do know of their physiology is fascinating. The Delirii carried their atmosphere within their bodies. Legend has it their own world may not have had one but that’s doubtful. More likely it was just very thin. Their skin was also made of a substance that hardened against pressure either inward or outward.
All of this meant that the Delirii had no need of space suits. They viewed the vacuum of space as one big atmosphere within which they moved freely.
