The black rock that builds it's way as one moves further from the open plains, until eventually the hot springs are reached. Constantly steaming, and some bubbling their is little by way of life in these pools. Lava tubes run under the rock here, fed by a constant supply of magma that surfaces occasionally through some hole or crack, either pooling briefly before being drawn back in when pressure decrease, or seeping out to eventually cool. Fire types love this area, and a few determined plant types can occasionally be spotted, though typically they are rooting plants like Bellsprout.
