Gyr Keela's assistant at the Mrlsst Trade and Science Academy was Gade Yedan. Yedan harbored significant disdain for Keela, believing the Mrlssi to be all talk and completely incompetent.
Yedan participated in the scheme to pilfer the blueprints for the Phantom Project's cloaking technology and to ruin Rogue Squadron's reputation. In this role, he answered directly to Loka Hask. Nevertheless, Hask killed him not long before a wormhole, generated by the gravitic polarization beam, engulfed Rorax Falken's laboratory.
