The layout is very similar to the parent instance, Nektropos Castle. However, you are forced to take a specific pathway due to blocked passages. Ultimately this makes for a very linear progression and it is hard to get lost.
Mobs randomly drop three different keys: copper, iron, and brass. These keys open up correlating chests throughout the instance, which each have a chance at providing loot. For example, an iron key will open the medium sized wooden chests.
Tinkering recipes (ex. Blueprint: Safety Recaller) have been found in one of the chest as well as boots.
Only the person opening the chest can get the loot.
Although this dungeon is level 50-56, the loot is mostly level 40 treasured items. Some bosses have broken loot tables which drop items such as the Bright Ember Necklace and Maltena's Brooch, which are no longer in the game. The exception is Lord Everling, who drops level 50 treasured items.
After a few turns in a corridor you arrive in a room with several ghosts in it, amongst them can be Butler Balthazen. Kill them and touch the door. The Burning Soul will spawn in the firepit. He sends you some soul ember that you need to kill. After 4 waves of minions, he will attack you. Killing him will unlock the other door of the room.
Reach Sheila's room. A ghost sent by her father will arrive and kill her. She will respawn as The Cursed Remains of Sheila Everling along with puppets. Killing them will unlock the door of her room.
