Xigeris

Ctesias, while speaking to Sergey in Coat of Arms, describes Xigeris as an "ill-tempered young man" indicating that he has a swath of jealousy residing within him, seen in Tidal Locking when he speaks to Nashatra about "taking his role" as a sleepwalker for the mission Nash undertakes in the events of Frozen Soul

Biography

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.

He wears a green valk, has both yellow skin and hair, wears a grey t-shirt, and blue pants
