Mmn, not sure...Caves in general are usually cooler than the outside climate, but if this one really is charged up with electricity like everyone says it is, it might at least be warmer than Mistralton Cave, with all that energy contained in it?

There might not be that big of a difference, though. Even with all that energy, it doesn't give off that much heat on its own...

Point taken, War-Rock...maybe it really won't be so warm in there...
