Mortal Shell II — Sester's Refuge (Monastery) Beacons: Entrance & Sisters' Gate

Published 2026-09-174 min read

The monastery of the Ruins of Mammon holds two beacons in Mortal Shell II — the Entrance and the Sisters' Gate — plus the red censer that unlocks Genessa. Route from the Outskirts, Map Fragment 1, and the quest staging explained.

The monastery — known in the world's own tongue as Sester's Refuge — is the haunted convent district of the Ruins of Mammon, and the source of the game's most important quest item. Two Beacons mark its progress: the Entrance and the Sisters' Gate.

Two beacons, one censer, one Shell waiting back at Marrow Keep.

The route

  1. Start at the Outskirts of Mammon Beacon and run the road toward the monastery, passing the tall tower position where Mammon Map Fragment 1 sits — grab it.
  2. Arrive at the monastery and cleanse the Entrance Beacon.
  3. From the Entrance, follow the route onward and cleanse the Sisters' Gate Beacon — the district's deeper checkpoint.

Why this district matters: the censer

The monastery's statue courtyard hides the red Sester's Censer, and touching it triggers a boss fight. Win, and the censer becomes a carried quest item: deliver it to the nun in Marrow Keep to unlock Genessa, the Wayward — the game's only quest-gated Shell.

The district's interior also feeds the Valley of the Revered road — the conquered temple region beyond the Sisters' Gate — so both Beacons earn their keep twice.
