Tigerstone Rift

The Tigerstone Rift, or Tigerstone Vale, is a nearly 700-mile-long rift valley in southwestern Orithea, lying between the Plain of Tharsus and the mountain ranges of northern Vastemar. Like the Druune Basin (from which it is separated by the Scyra Highlands to its east), it lies well below sea level. Much of it is filled by the enormous Lake Lhodogir. The rift and the lands around Lake Lhodogir’s shores are typically considered a part of the greater Kelimarian region; if a distinct line between Kelimaria and Vastemar was to be drawn, most would put it along the rift’s southern edge, where the bottomlands begin rising up to the craggy peaks of the [northernmost range of Vastemar] in a series of dramatic, step-like escarpments. Most of the people living in the rift are of Kelim origins.
The Tigerstone Rift has a warm, rainy climate, bordering on subtropical, and much of it is covered in lush forests. Its name comes from the abundance of tiger’s-eye gemstones which can be mined from rich veins along many parts of its steep southern walls.
