"Do you really wish to know?" — Spoilers from the books and/or adaptations to follow!
This abandoned site is situated at a crossroads west of Lurtch and is overrun by renegades. When liberated, 120 + 50 is awarded, and some refugees will move in along with a herbalist and merchant.
This is the location where Letho will lead Geralt to during the secondary quest Ghosts of the Past. Regardless of its previous state, for the duration of the quest the place is occupied by Louis and his band.
