Xigeris was an immigrant residing in the United Places of Robloxia before presumably being scouted by the
Rose Seekers. However, he seems to have been rejected by them in favor of Nashatra. It is unclear how he died, but it'
s clear Nash feels some sort of
heavy guilt related to him as seen in Tidal Locking, as when you fight or defeat him, he is seen as a mirror that can be shattered after wearing his hat, either meaning Xigeris was trying
hard to be her so he can be accepted by the
Rose Seekers and/or he turns into a
mirror copy of Nash (when you do not wear the hat), as like she's fighting herself over his
death. The fact you can find his hat in the hellish world of Bloxen probably alludes to the circumstances of his demise. It is also possible the presentation of Xigeris in Tidal Locking is not actually his true persona, but Nash's conception of it, as it is a memory world.
"There was a time when Midas could have had his own salvation. His confession would be a turning point for the banal. Midas goes to his backyard, takes off his helmet, kneels, and for the first time it looks like he is going to do a
noble, superior human act. But he digs a hole and puts his
face in the
earth, quietly confessing "I have donkey ears". In that hole a reed grows, a watery grass that goes where the wind blows, the reed echoes from the
bottom of the earth, excited by the wind, the trivialization of that life that has no center, that does not grow anywhere, that goes where the wind blows. This is the story of the banal man."
