Ren can still organize a fake death for himself if he gets annoyed by being into the light or he could use the mask he stole from the thief at the auction house.
Ren is on for trouble after the Battle Royal. Though, I don't know if he really wants to use the Void Step at that moment or he just uses it because of the influence of Monarch Indifference.
Thank you for this amazing story man, the chapters are an ideal length, very good grammar and a good dose of suspense to increase my "hype" for the next one
