Politics
Siraganon was designated as the rendezvous point for the Emperor's tour, where the Imperial fleet and the Jaddian fleet of Prince Kaim were directed to assemble. The world lies approximately five years of warp travel from the DB-639 region near Ganelon, with Fidchell serving as a refueling stop along the route. A Cielcin force of seven worldships attacked the Emperor's fleet at Siraganon and at Perfugium simultaneously. Following the initial assault, the Cielcin commander Dorayaica appeared in holograph above Siraganon projecting a mile-high image to demand the Emperor's surrender.
