Nasta held dominion over the subterranean operations on Mrlsst as a humanoid, during the initial period of the New Republic. This awkward, avian-resembling entity, characterized by deep brown skin and prominent eye sockets, aided Rogue Squadron in revealing Loka Hask's schemes. Nasta accomplished this by leveraging the monitoring systems within the Mrlsst Trade and Science Academy to observe Hask's strategic planning sessions.
