Terrand Neyrr was a dark Jedi who turned from the Jedi Order at some point after Order 66. What his exploits were during his time as a Jedi, and prior to his becoming a member of the Order of the Sith Lords, was left to mystery. Darth Odium later put Terrand to use as a forward operations agent for the Order of the Sith Lords, and even considered him a likely candidate to succeed Darth Dolosus as his new apprentice. Despite noting Terrand's skills, however, Odium chose another instead.
