But that, my dear Vergil, would be what I like to call "Metagaming." The most obvious and present threat is the gas being dispersed in the atmosphere, and Orin has NO idea what a Tamaran is, let alone that there's one nearby.

He knows what they look like, and his first priority is going to be making sure that he's still fit enough to fight.
