activity
Go to Silts Tower, at the south-western edge of the map.
Enter the ground-floor door and climb to the top.
Interact with the door at the top — this is what costs four segments.
Fight through the flashback and beat the Gargoyle boss.
To leave for good: at the second group of enemies, inspect the well in Focus Mode and follow the voice.
Through the portal, help the priest remember by inspecting Alin, then Esme, then Coen.
Inspect the red glowing tree stump, clawride down to the river, and finish the conversation.
Only what a source states. A quest with nothing listed is a quest whose rewards are unpublished, not one that gives nothing.
Playing the flashback through four times in a row instead of escaping traps Coen in the dream and triggers a secret ending — with an achievement attached. It is highly missable, and it is not the way out of the activity.
Only one source describes this, and it is the strangest entry in the catalogue: a hidden Court activity that is also a flashback, a boss fight and a route to a secret ending. Four segments is the door alone; nothing is published for the level beyond it.
