Ages have passed since the peaceable Melem learned to harness the Fathom Orb, imbuing themselves with a trace of its baleful energy to enable “Ghost Walk”—a momentary phase-shift into another dimension. Even when they were sieged by hulking, chitinous marauders, the Ghost Walk saved them as it had many times before. Then, the unthinkable: One of the attackers returned and breached the Orb. With no alternative, the Melem broke their inviolable law and sent their most skilled assassin to the Fathom Orb, not knowing whether she would survive, let alone how she might return.

Nyx takes a walk on the extradimensional side with her Ghost Walk active ability. Slipping momentarily out of the Dreamlands, Nyx is able to avoid incoming attacks, sneak around threats to get a better angle, or even perform a lethal telefrag when she rematerializes. Should she reenter the Dreamlands in the same physical space as an enemy player, she destroys them from the inside out in a gory spray. While Ghost Walking, Nyx is invisible and invulnerable to all damage.

When a jump is just a little too far, Nyx has the solution. Having mastered the art of wall jumping, Nyx can make contact with a wall midway through a jump and perform another jump, doubling her distance. She can even do this while Ghost Walking to move quickly and stealthily through her environment.
