D-Three
this was the designation of one of the Dreadnaughts that was part of the Outbound Flight starship. D-Three was one of the five Dreadnaughts which was buried when the ship crashed into a large planetoid in the Redoubt, after it was attacked by a group of Chiss led by Thrawn. During the crash, the turbolift pylons connecting D-Three to the rest of the ship were damaged, virtually cutting it off from the other five Dreadnaughts. Because of this, it was in D-Three that the Outbound Flight Colony established an isolated prison for beings suspected to have some connection to the Force. If these individuals actually exhibited some control of the Force, they were first sent to the Quarantine on D-Six. There, potential Force-sensitives were tested. Any member of the colony who exhibited a strong connection to the Force was then incarcerated in D-Three to keep them from acting against the rest of the colony. It was believed that only two individuals had ever been sent to D-Three, although many wanted Evlyn Tabory to be sent there, after she was discovered to have the ability to use the Force.
