Robby

Robby is Captain Willis's son. He is found cryo-frozen in a bunker, and his terrifying nightmare is the source of the DLC's central conflict.
(Robby and his father, Captain Willis, were on a Dahl ship above Elpis when the moon was teleported away, sending their ship crashing into the planet Kairos. During the crash, Willis got separated from Robby and was unable to find him.)
