Biography
Phanius was known to be intelligent and charismatic renegade of the Jedi Order. He practiced the elements of moral relativism and solipsism, possibly echoed in certain aspects by the much later Potentium.

Years later, he abandoned his oath and left the Order to pursue prohibited teachings, became known as the Lost Twenty. This eventually turned him to the dark side and served in the New Sith Empire. Before the Ruin's Sith Order quickly disintegrated, he redeemed himself back to the light until one of the sith killed him before he could save everything for what he's done.
