 Utegetu Nebula
The Utegetu Nebula is a relatively new nebula in the Galaxy. As all nebulae, the Utegetu Nebula was formed by a supernova which was still in the process of cooling when found. The Nebula was found by the Solos when they were laying a trap for Alema Rar to reveal herself as a Gorog Joiner. The planets there seemed to have been unharmed by the supernova but this is probably because of the Fizz.
After the events of The Joiner King the Killiks were relocated to the Utegetu Nebula. Unfortunately, the Ithorians needed a new home which was to be The Utegetu Nebula because of how it was undiscovered by anyone and that there was considerable, and violent, competition for planets to terraform for displaced refugees.
The only entrance to the Nebula is through the Murgo Choke, a system with four different types of stars. It can easily be blockaded, as in The Unseen Queen. There are two other places of interest in the Utegetu Nebula. One is the planet Woteba, named after the Killiks moved there. This is also where the Solos laid a trap for Alema Rar. The other is The Tusken's Eye where the Gorog led the Hives into the creation of a fleet of 11 well armed battle/hive ships.
