U — Ruins of Berez
A swamp where a house used to be — or rather, where Morgantha's house stood above a structure far older than anything she built. The party arrived here in [session 9](/curse-of-strahd/sessions/session 9) and has been in and around this location through [session 16](/curse-of-strahd/sessions/session 16).
Above ground: Ruins, swamp, the sinkhole entrance to the vault below. The tunnel the party entered through was collapsed by Logi (Cinder growing restless in the enclosed space). The only way out became the sinkhole — which opens onto moonlight.
The Memory Vault
The party departs this location in [session 16](/curse-of-strahd/sessions/session 16), heading east on the Old Svalich Road toward Castle Ravenloft.
