12.2 THE PRIME MATERIAL PLANE
Most of the adventures on the world of Lusternia will take place in the Basin of Life, an enormous continent surrounded by a circle of mountains. In the center of this basin are two inland seas, and surrounding that great highways that are the arteries of commerce and trade. Presiding over all is the towering mountain known as Avechna Peak, situated to the northeast among the northern mountain range, a holy site where many pilgrims travel. The prime material plane is adjacent to the ethereal plane. See also PLANAR TRAVEL.
