Tythian Massif

The Tythian Massif is a large section of elevated, mountainous highland dominating the southeastern corner of Rhydain, the region called Tythium (from which the massif takes its name). It is also sometimes called the Tythian plateau. The massif is dramatically ridged with a number of high mountain ranges and furrowed by the deep, steep-sided valleys that narrowly separate them. The greatest summits of these ranges are nearly as tall as the major peaks of the Adhemars, and most of the ranges are snow-covered year round. The dells and valleys of the massif are typically filled with pine forests, with swift, cold rivers rushing over rocky courses and plunging down impressive falls. 
All around the edges of the Tythian massif, this rugged terrains drops off abruptly. To the west, it gives way to the lower and more rolling hill country of the Lokenmoor. To the south, the high peaks descend in a dramatic escarpment to a belt of foothills which in turn flattens into the Alondrian coastal plain. To the east, the mountainsides run straight down to the sea, almost cliff-like in many places, giving the western shore of the Shreenwater and the Dragon’s Jaw a steep, rocky character with sheer bluffs and jagged promontories looming thousands of feet over the crash of the surf. To the north, the Tythian ranges slope down into a chain of lower peaks, marking the transition to the Mountains of the Morn.
