The Astral Tunnel is the final dungeon in MARDEK Chapter 3: Keystones. It's currently the only accessible place of the Astral Realm.


After the King of Goznor's death, Qualna reveals himself as Clavis, and he tries to escape to Anshar through an Astral Tunnel, asking Rohoph to return with him to help save Anshar. Rohoph does pursue Qualna, but only to kill him. He then casts a spell to prevent Qualna from Soul Transferring.
