Sea cave

The sea cave is a location in Point Lookout, entered through the wrecked seatub or the well outside the Ark and Dove Cathedral. Tribal leader Jackson uses the cave to communicate with a hologram of Professor Calvert.

Layout
The cave consists of a series of passages leading to a main chamber, where Jackson communicates with Professor Calvert. The sea cave is inhabited by swamplurks, mirelurk hunters, and swamplurk queens. Additionally, a lone unnamed friendly tribal wanders the cave and will follow the Lone Wanderer around if he spots them. However, the tribal will often be killed by mirelurks before encountered.
