exar blowing up suns

This question is mainly to lord darkstar but fell free to say something.

Excuse my ignorance on exar kun but where how and when did he blow up a sun.Im just curious.

It was in the Dark Horse Comics. Ive seen the pages on the internet somewhere. He did it to kill some chick. To my understanding. And i think it was during the Hyperspace Wars... Or when the Republic came after the Sith in some war... I cant remember.
