This article concerns a location that appears only in The Witcher computer game. Its contents might therefore contradict information from Andrzej Sapkowski's books and other adaptations.

The Lionhead Spider Cultists' lair is a crypt in the sewers of Vizima which is behind a locked gate. Fortunately for Geralt, and unfortunately for the dead knight, there is a key to this lair to be found in the knight's remains.

Once inside, Geralt must break down a few flimsy stone walls using Aard (the ones which can be "blown down" are truly flimsy looking, none of the more solid obstacles can be removed) and fight off around a dozen or so cultists to get to the booty. This booty is concentrated in two chests, and each chest is in a heavily guarded room.
