Tephra Cave

Tephra Cave is a large, cavernous area that you will be forced to visit at least twice during the main story. The main entrance is located up a hill just outside of Colony 9 and during your first visit, there will be a locked door inside. It isn’t until your second mandatory visit, which happens not soon after the first one, that you can explore beyond that locked door.

Once you clear the Mechonis Core section of the main story, a high level area will open up for exploration. You can access this from Vilia Lake, with the landslide that was once there being gone.
