Darth Ramage was a male Dark Lord of the Sith and scientist who was part of the lineage of Darth Bane. During his lifetime, Ramage created a Sith holocron that contained instructions relating to the combination of bota and pyronium. Ramage also performed experiments on the Cephalons, a sentient species that could perceive past and future events through time, to explore the possibility of harnessing the power of time travel.
In 18 BBY, Darth Vader attempted to track down the holocron after it was stolen from him, since he believed that Ramage's instructions would aid his efforts to use bota and pyronium to augment his connection to the Force. While Ramage's instructions would have been helpful to Lord Vader's quest, they were not vital, and Vader was unconcerned when he was unable to recover the holocron.
