Ellefrin Vrax was the Orion manager of the Yoshitoni Institute, an Orion Syndicate-run mercenary training facility. Vrax was known for his perverse sense of humor, and he ran the Institute as a parody of a legitimate institute of higher learning, complete with graduation ceremonies with caps and gowns, with himself as Dean. Even the name 'Yoshitoni' was a joke reference. (Last Unicorn RPG module: Raiders, Renegades & Rogues)
