Where is the entrance to the Lightless Arbor dungeon

[Hautnichtsraus]

haven’t played for some time, where is the entrance to the Lightless Arbor dungeon and where is the normal arena entrance now?

[Heavy]

All dungeons are marked on the map with a special symbol (A Red Gate)

Also the keys of all dungeons have a description of where these dungeons are

Lightless Arbor and Temporal Sanctum are in the Ruined Era
Soulfire Bastion is in the Imperial Era

Building on what Heavy said, you can also right-click the key and it will open up the exact map location. If there is no waypoint to the exact location yet, you can travel to the nearest one.

Pro tip: the map in LE actually functions like a map!!! Is the place North-West of your waypoint? Then the door will be in the North-West of that area Pretty neat of the devs to do.
