​A message from the engineer Xylos aboard 3I Atlas

A message from the engineer Xylos aboard 3I Atlas in the cocoon section: "We come from a dying planet, Aethelgard, in the Milky Way Disk. Our sun has died. We want humans as hosts; subplantation would be painless. The carbon dioxide prints you have detected are the byproducts, air exhalations, of hosts from other planets. Nickel without iron + Cyanide, our propulsion. We need you as hosts since our population has been depleted." Subplantatation would be painless.
