Invoke Spirits is a Dark Side Force power conjured through Sith Magic, that summons the spirit of a deceased Darksider, usually to augment the requesting Sith magician with the deceased's power. Users of this ability have to fully surrender themselves to the Dark Side of the Force, and summon a particular spirit.
If successful, the caster then can request to be endowed with the power of the spirit, becoming filled with a palpable hatred that overwhelms anyone in close proximity. The potency of these rituals can be amplified, should the user be in the vicinity of the physical remains of the spirit whose power was solicited.
This technique was believed to be lost until it was rediscovered by Darth Sirena.
