Dreamer (Sith Legend)

The Dreamer was a Sith of Sith Legend.

In the legend, The Dreamer duels with rival Sith, The Monster-Slayer. The duel ends with the death of both, overwhelmed by the vapors of the Pits of Paxxis.

According to Luke Skywalker, the legend was rooted in fact, and took place circa 3400 BBY.

At some point, a depiction of The Dreamer's duel against The Monster-Slayer came into Skywalker's possession, which he annotated sometime after the Emperor's death in 11 ABY along with a copy of The Jedi Path and Book of Sith.
