"It is a valid scientific approach to not believe something until offered proof. It can be a theory, but it is not a solid truth until proven as such."

Tieria shrugged lightly. His thought process wasn't designed for the mystical arts. Tieria worked in absolutes. If he didn't have proof of something, then it couldn't be anything more than just a working theory. He preferred numbers and tangible things, plans, results, stuff he could measure over things that were more abstract and spiritual in nature. So, sure, those things could potentially exist back home for him, and there were still many in his world that believed they did, but nothing had convinced Tieria beyond a doubt that they did, so he shelved them.
