Attack upon the Kasterborous constellation

The attack upon the Kasterborous constellation was a battle towards the end of the Last Great Time War between the Dalek Empire and Time Lords. (PROSE: Dalek) With the Daleks having pushed the Time Lords back to their homeworld of Gallifrey (PROSE: The Day of the Doctor) after an eternity of conflict, (PROSE: Engines of War) they were able to attack the Kasterborous system (PROSE: Dalek) where Gallifrey was located. (TV: Pyramids of Mars) Whilst a Dalek Commander involved in the engagement was killed, the battle ended as a massive Dalek victory, (PROSE: Dalek) giving the exterminators the chance to attack Gallifrey itself. (TV: The Day of the Doctor, et. al) Upon learning of the destruction of its Commander, one Dalek drone under its command came to believe the officer had died fighting bravely and that it must have died for a specific reason. With the commander dead, the drone and its squad was given a new Commander. (PROSE: Dalek)
