Dar will tell you a short tale about the Swarm.
The Sith invasion was preceded by a single black rock falling from space. The Swarm was unleashed and much devastation was brought to the planet. Originally both the Bollans and the Garans stood strong against the Swarm, brought together by the strong leadership of the Vaka (Bollans) and the Hsrik (Garans) of the time.
However, the Hsrik was corrupted by power when the Sith arrived. They offered him the planet if the Garans joined the invasion forces.
The Jedi came in defense of the Bollans and a tremendous war was fought that destroyed every city on the surface of Boll-Gar, reducing it to the primitive state it is currently in.
Eventually, the Sith left but the Swarm remained, now uncontrolled and wild.
"That much is known and clear," Dar says. "The names may be lost to time but the basic history of it can be supported, if we were to look. From there, it gets... unclear."
