The rainbow comets of the Cloak of the Sith nebula were for centuries the only method for finding safe passage to the planet Roon. Annually, the comet would find its path through the hazardous spaceway on its way to briefly orbit the system's sun.
Explorer Mungo Baobab gained much notoriety from following the comet as a means of rediscovering the Manda-Roon Merchant Route. Following this brave pioneering effort, a series of lightstations were put in place to guide future merchants and visitors.
