Akoum

Akoum is one of the seven continents of Zendikar. The region is geologically unstable.

Akoum is a mountainous continent where magma glows from crevasses in the earth. Crystalline fields shimmer beneath the sun, but the sharp edges of most surfaces will slice through skin and bone. In some areas, the temperatures are extreme—burning an explorer's skin during the day and causing frostbite during the night. Gases occasionally spew from the ground, and around these vents, bizarre trees and plant life have arisen in pockets of weird biome. The region is plagued by geological instability, causing magma geysers to erupt unexpectedly and shards of rock to rain down unexpectedly.
