He is an alien humans call Architects. He is curious about every little thing and he doesn't understand simple human concepts like music, dreaming, sarcasm, and other such. He finds human bodies inefficient. However Robin has taught him a lot about that, so he is slowly understanding more and more. He cannot have Alterra know of his planet though. He lives on a different planet of unknown name, but for now he is on planet 4546B, which he calls Subnautica. Curious about every little thing.
