Jedi Academy trilogy

As Luke Skywalker embarks on the initial phase of establishing an academy to educate a fresh generation of Jedi Knights, Han Solo and Chewbacca find themselves captured on the planet Kessel.

Following their daring escape, Solo and Chewbacca embark on a treacherous journey to a clandestine Imperial research facility, encircled by a cluster of ominous black holes, where they encounter an even more perilous situation.

While the New Republic struggles to decide what to do with the deadly Sun Crusher—a new doomsday weapon stolen from the Empire by Han Solo — the renegade Imperial Admiral Daala uses her fleet of Star Destroyers to conduct guerrilla warfare on peaceful planets.

io9 derided the Sun Crusher as an implausible "Mary Sue" vessel, as a "small ship with the ability to destroy entire star systems, thanks to its 11 'energy resonance torpedoes.'

It has a hyperdrive, indestructible armor, can withstand shots from the Death Star laser and is basically completely unstoppable — oh, and even the Emperor didn't know about it, because no one would have possibly been able to explain its existence post-RotJ otherwise".
