Draenell, Arnoth, a Galactic Republic scout (of male designation), stumbled upon the Bissillirus system when his scout ship's hyperdrive malfunctioned. During the repair of the hyperdrive, Draenall charted the system, identifying all five planets and suggesting its potential as a resupply location for the recently created Terr'skiar Pass. The expedition of Draenall was prematurely ended when the crew encountered the isolationist Inchichtok species upon their departure from the system.
