The Helvellyn Clan claims the upper reaches of the Helvellyn massif in the Lake District, their hidden domain stretching from the shadowed crags of Striding Edge to the glacial hollow of Red Tarn. Few outsiders ever glimpse their true lair… a network of volcanic caves concealed by treacherous rockfalls and swirling mist. In summer, they prowl the ridgelines where the wind masks their scent; in winter, they retreat to deep geothermal caverns near Glenridding Beck, warmed by hidden hot springs.
In ancient times, they were known as Felllyn. The Vikings called them Cait Sidhe. In the modern tongue, they are known simply as werecats.
