Imperial Civil War

Following the destruction of the third Death Star, trouble began brewing on Imperial-held Mon Calamari. The planet was eventually completely taken over by a man claiming to be noneother than Emperor Palpatine. Palpatine began rallying thousands to his banner in outright war on Valak, deemed a traitor by Palpatine.

The Empire became split, Athaniss and numerous other star systems falling over to Palpatine over a period of a few weeks. Athaniss became a massive battleground in the war, fought over three times until it finally fell under Palpatine control.

Ultimately, however, the New Republic intervened, liberating Mon Calamari, allowing Valak to regain territory himself until Palpatine was cornered to Athaniss. In the final battle, Palpatine was captured and revealed to be an imposter, and soon executed by Valak.

The Empire was brought back together, but the wounds inflicted would never fully heal.
