sadly wise mystical tree man does not open his eyes as he is taking his yearly allotted 15 minute kindergarten nappie, but we could try beringer (unless extracting the curse means the eyes revert back)
personally I believe the inferno curse user would have much brighter blazing blue eyes. His eyes are most likely dark blue as that’s a trait of natives of the Azura Province (azura > azure > sky blue)… on a second thought azure means blue like the sky… could Azura be another sky island nation???
