Masteria Expansions, Names and the proof for each

I'm pretty sure Glimmerman is an alien. In that quest when he tells you to go see Elpam and Glimmerman, The Glimmerman said that he has travels many worlds. But if you keep reading all the theorys he has on the Communique was from allien worlds such as a slug world and something else that i cant remember right now. After you finish talking to him he asks you to go see Elpam so if he was versalian then he would have figured it out instead of making you to go Elpam
