Windward is far wetter and more hospitable than its larger and colder sibling. Currents of water from the south keep the clime temperate, while the mountains capture much of the moisture coming from the western ocean. The forests here are temperate rainforests, with boreal forest covering the leeward eastward sides of the extinct volcanoes that form the ridges. In the high mountains, constant clouds and mists make for a unique ecosystem – one where it rarely rains but is never dry. Complex and dangerous cave systems pock the mountains and serve as a last-resort hideout.
