Eastern Mountains Known as the "Waterwall Mountains" by the non-demihumans, these form the boundary between the Western Kingdom and the Frontier. The foothills below the mountains, particularly the area east of Hillsburrough between the North and South forks of the Eastern Arc River, have already seen many large battles between expanding demihumans and monstrous bands - even a few armies claiming that they were sent by the Great Alliance (thought broken up 300 years ago by the Council of Nine). The Eastern mountains still really aren't safe, despite all the traffic they see. In addition to the bandits that haunt the lonelier corridors of the Frontier Road, there are all manner of known and unknown monsters that lurk in the higher portions of the Eastern Mountains. White Worms, Frost giants, and Drow all haunt the mountains. Rumors of dungeons and evil castles popping up across the mountains are increasingly common, and the nature of the mountains - with their high peaks, steep slopes, and few navigable passes - make these rumors difficult to investigate, let alone confirm or squash. Regardless of any of this, the Eastern Mountains are definitely proving to be the passport to the future of the Kingdom, for better or worse.
