[quote] In time his kind would be called Titan[/quote] doesn't get anymore obvious than that.

good point. also we don't have any specific time periods given. this might have been earlier. but appearance/robes is no justification for one belonging to a certain class. look at eris. most of the destiny community believed she was a warlock for her appearance, but she is a hunter. same might be here with a titan wearing warlock robes for maybe comfortable reasons :)
