Three hundred years after Tulak Hord, the Sith Ergast tried to recreate the ritual the Dark Lord used to devour the spirits of his enemies at Yn and Chabosh. In its place, he discovered what he called the ritual of Force-walking.
Requiring a Sith of great strength of will, the ritual of Force-walking allows the user to bind the restless ghosts of dead Sith to himself. Once the ghosts are bound, the ritualist may draw from their power, channelling it into a powerful exertion of Force energy against his enemies.
