Our experiments are going better than hoped. The children we've warped have been most interesting test subjects. Earlier today, #8 managed to drain the life of one of the prisoners you sent us. #3 and #17 have shown great usage of Force Horror; however, they have little control, affecting one of our researchers. I'd appreciate it if you could send your apprentice, Darth Judicar, to inspect the place and make sure everything is going how you want it to.
—Barrel's report to Aevum
Dr. Barrel was the director of the space station Lacrima. He had been present when Sith hopeful Geist Weiss arrived at Lacrima hoping to join the Sith. Though Barrel was skeptical of a Cinnagaran nobleman wanting to join the Sith, he eventually allowed it and transferred him to Darth Crysis.
Years later, Barrel would meet Geist Weiss again when Project Saligia took place on Lacrima. Barrel work alongside Weiss, Darth Kayos, and Sia Zle'tey. However, when Weiss and Kayos were gone for a trip, a test subject went out of control, turning the staff insane. Barrel managed to survive for a while but died before Augustus Primus Leonus and Elkaid found him.
