Players in Crimson Desert complete the Mystical Key quest by locating a key to unlock a hidden room in Hernand Castle. After this, they activate the Abyss Nexus in the Abyss by stepping onto a pad and receive the Axiom Force ability from a white crow. To use Axiom Force, players aim and attach it to discs on the floor, manipulating them to create a circuit of blue light that unlocks the next area, allowing them to proceed to the Abyss Without Balance quest.
