Darth Rivix

History
Darth Rivix served in the Sith Empire as a Sith Lord and after the Battle of Corellia in the Third Galactic War and the subsequent disappearance of Darth Malgus, Rivix was then appointed by Emperor Vowrawn to act as the liaison between the Hand and the Eternal Alliance.

He arrived on Odesson with a small force and greeted the Alliance Commander via holo and told them that they must be expecting him and wished to speak in person and had his shuttle land in the hangar where he was greeted personally by the Commander.

Darth Rivix informed the Commander that he was merely there to assist the Commander in their missions and anything he reports back to the Emperor will be at the behest of the Alliance Commander. He then requested a tour of the base before they got down to business in the operations room.
