D&D 3.0: Tales from Mystara
Mount Kala is an active volcanic cone on the site of a catastrophic second century BC eruption located on Honor Island on Ierendi. Subsequent subsidence caused an island the size of the Five Shires to sink into the ocean, leaving three smaller islands like Honor Island, Elegy Island, Roister Island above sea level. All native plant and animal life were destroyed in the Great Eruption. A bleak jumble of jagged lava flows, cinder fields, and barren volcanic slopes, Honor Island was never repopulated by Makai natives or mainland immigrants. Only the hardiest of plants grow here, occasional sprinkles of green against the bleak, black volcanic landscape.
