Generally, Imbros doesn't really like being wet, and handles it with all the aplomb of a cat that fell in a bathtub. But hot springs are a whole different thing. When his adventuring party found one in his realm he had to be dragged kicking and screaming from it; fully ready to live there for the rest of his life.

So when he finds out there's one here, there's no hesitation as he sets out looking for it. Who cares about the barrier, or the cult, or his current mission to learn necromancy when there's steamy water to sit in?

Turns out someone else had the same idea, "Good morning," he says politely as he walks around to a further side of the spring to put some distance between them, dropping down to his feet to walk rather than levitate so she can hear him. He's too self-centered to ask if he can join her, but he does at least attempt some sort of pleasantries, "I'm surprised more people aren't here. Especially if they're all sleeping with dirt in their beds."
