Unbeknownst to many at the time, Tenebrae was, in fact, the elder Dramath's illegitimate son, and therefore Dramath the Second's half-brother. After killing their father, Tenebrae sought to destroy Dramath the Second as well, but the Sith Lord fled Medriaas with a group of followers, and made a new life on the snow-swept world of Rekkiad.
Dramath the Second eventually died on Rekkiad, and his disciples entombed him in a hidden crypt found in the first of the two plateaus that comprised the Twin Spears. Over one-thousand years later, a Sith working on behalf of Tenebrae was led to Dramath the Second's crypt by Mandalore the Ultimate.
