A wary Igalyph, Masma is often alone by choice. He has trouble trusting others and is sensitive to emotions. If someone with a powerful aura is nearby, Masma might cower and shake in a hiding spot.
He has a nook in his cavern wall where he stores his odd collectables, mysterious items or common household ones for other lythians. Typically shiny or intersting bits and baubles. Gold catches his eye more often than other precious things.
