Even if his past wasn't that interesting, Elim didn't see the need for him to disclose it with everyone there. Elim didn't require any new clothing from the Prince since he was already prepared, his armor and whatever other clothing he had on beneath it helping to shield him from the cold rather easily, a scarf wrapped around his neck and loosely around his mouth to help keep the chill of the winter's air out of his lungs, something that was a bit detrimental in combat and something that these other people weren't really considering. Well, it wasn't Elim's problem if they died, but then again it also could be since Elim didn't know how to pilot the Gummy Ship or whatever it was called. 

"My name is Elim, that is all you need to know about me." His voice was a tiny bit stifled by the scarf, but it was pretty clear what he said, and in the tone he said it the boy sounded as though he didn't want to be bothered with petty conversation as he continued to move forward with the others. "Also I don't know if its the same here, but wintry regions like these tend to house more than just those Heartless creatures. We should also be on the lookout for wolves and any other form of arctic creature." Elim was silently hoping that there would be no ice wyrms or other such deadly creatures here. He also hoped that this world didn't house any Frost Giants or even Elder Frost Elementals, since this was apparently a sorcery conjured ice storm. Elim figured as long as they didn't run into anything like that, then they would be fine.
