‘castle of eastern winds.’ (Svt) large fortress located in a rocky passage in the far-southern region of the Greymist Hills along Serathyr’s northern border with Elyria. The castle was built in the early Sixth Age by the Serathian royal court and is now manned by the Serathian army. The fortress keeps vigil on the Elyrian outpost of Wymerly Keep. This fortress played a key role on the terrible War of Four Kings, and currently is the base for many covert Serathian raids into Elyrian territory.
