A few hours before ...
"It's a trap," said an officer as he watched as the UG ships were pulled out of hyperspace, Jedi Master Akania Orel knew what was happening and knew that the only way to make medical ships and transporters escape was to use the Aeternal Light and the 2 venators that remained as shield and distraction, while the others escaped. So it was.
"Divert all the energy to the frontal shields and to the motors, it is necessary to do time" said the Jedi master, the Aeternal Light began to go against the ships of the Empire. At maximum speed, the Aeternal Light would not take so long to ram the imperial destroyers.
As a last act of will, Akania asked the Jedi Council to involve the entire army of the republic, since Thrawn and the dark side can not win.
... A great explosion occurred as a result of the clash between the capital ships, the Aeternal Light and an Imperial Destroyer lie destroyed in space.
Much of the Republic's Fleet of Exploration managed to get away in time from the star that was about to explode, they lived to fight another day thanks to the sacrifice of the Jedi Master.
