Claustrophobia

Claustrophobia is a music track unlocked in the Arzinian Mines during the Between a Rock... quest. Upon entering the mine through Dondakan's dwarf multicannon, players will automatically unlock it.

After defeating the Arzinian Avatar and completing the quest, re-entering the Arzinian Mines by entering the mines south of Keldagrim will unlock the track In Between, which plays instead of Claustrophobia whenever revisiting the site.

The track itself is named after the anxiety disorder claustrophobia, the fear of being trapped in a small space. As the track is unlocked in a mine, this is somewhat fitting.
