Summon Darkness is a Dark Side Force power conjured through Sith Magic that creates visible palpable waves of literal darkness, accompanied by a loud roaring sound. Performed by an individual adept in Sith magic, the wielder can summon the power of the Dark Side, using it to visibly immerse the sky and atmosphere with total darkness. This dark power then manifests itself in the form of a storm cloud, complete with rolling claps of thunder. This technique was believed to be lost until it was rediscovered by Darth Sirena.
