Location from The Witcher by Andrzej Sapkowski
The crumbling Wolf School fortress hidden in the Blue Mountains — last refuge of a dying witcher order, where the Trial of the Grasses once created monster-hunters and now only ghosts and memories remain.
Kaer Morhen is a monument to everything the witcher profession has lost. Built to house hundreds of trainees, it now shelters a handful of survivors who return each winter like migrating wolves to a den that grows emptier each year. The fortress's lower levels are sealed — flooded chambers, collapsed tunnels, laboratories where mutagens were prepared in an era when witchers were manufactured by the dozen. Those secrets died with the mages who created them. Cold drafts carry the smell of damp stone and ancient alchemy through corridors too numerous for the remaining witchers to patrol. The courtyard where boys once trained until they broke or transformed now serves as a sparring ground for three men and their memories. It's a haunted place, even without actual ghosts, though it has those too — and on winter nights, when wind howls through the Blue Mountains, the fortress groans like something alive that remembers what it was.
A massive stone keep in advanced decay, perched on a mountain shelf above a winding valley approach. Collapsed towers and crumbling curtain walls frame a courtyard still used for sword training.
