The Dark River
This is the Lloydable room in Noctopia and the only way to shift directly into the plane.
Anchor is very commonly set to give access to Noctopia gear runs without having to go through the death trap that is Shiftwatch Orb. If the anchor is here, it's advised to NOT move it elsewhere as a large group spent a decent amount of time setting it here. Be forewarned, when shifting into this anchorpoint, the ethereal stalkers will begin hunting those that shift in. They hit extremely hard and bash liberally to boost theirs and other mobs' damage.
To reach this room from the waterfall, the directions are wnwn4w2n.
The room is identifiable by the mention of the shiftwatch orb floating above you in the room description, in case you get lost and do not have detect haven available.
It is a noregen room, so while you can shrine it it serves absolutely no purpose.
