Darth Plagueis, publicly known as Hego Damask II, and remembered as Darth Plagueis the Wise, was a powerful male Muun Dark Lord of the Sith hailing from the planet Mygeeto. Damask was born between 147 and 120 BBY to a female Muun and a male Muun. His mother discovered his sensitivity to the Force, and she gave him away to the Bith Sith Lord Darth Tenebrous, who trained Damask—now Plagueis—in the ways of the Sith. The apprentice murdered Tenebrous in 67 BBY. Rising to become a Sith Lord, Plagueis, acting as the leader of Damask Holdings, a financial corporation, manipulated galactic affairs and corporations to advance the Sith agenda and the Galactic Republic's fall. While manipulating the Naboo on the planet Naboo, he discovered Palpatine, a man with the desire to rule. Plagueis manipulated the boy to kill his family, which led the young man to accept Plagueis's Sith training. The master and apprentice continued the Sith agenda together, with Palpatine saving his master from many assassination attempts, however, Palpatine, now teaching the Zabrak Sith apprentice Darth Maul, wished to kill his master and rule the Republic alone. Celebrating that the manipulated senators and bureaucrats of the Republic had voted Palpatine as the new Supreme Chancellor, Plagueis was killed by his apprentice in 32 BBY while the Muun slept.
