A southeastern drainage from the Caffas range, the Elmynfrosk flows through the eastern White Wastes before reaching Pugrai Naihim. The river's character changes as it approaches the coast—the stillwater effect from the Pugrai lakes extends upstream, slowing the current to an eerie crawl for the final miles.
Orc and goblin tribes use the upper Elmynfrosk as a water source but avoid the lower reaches. They claim the slow water is a trap—that things wait in the sluggish current for prey to wade in.
