Mon Cala

Mon Cala, also known as Mon Calamari or Dac, was an oceanic planet located in the Mon Calamari system, a binary star system positioned in the Calamari sector of the galaxy's Outer Rim Territories.

Description
Although some cities on Mon Cala were built underwater, there also existed cities built on the surface of the ocean. The planet was inhabited by two separate sentient species, the peaceful Mon Calamari and the more bellicose Quarren, and was ruled over by a single monarch. Despite their differences, the two peoples had respected each other for the longest time.

Clone Wars
During the Clone Wars, the eighty-second King of Mon Cala, Yos Kolina, was murdered. While his young son, Prince Lee-Char, was supposed to take the mantle, the Quarren refused to accept him as their leader due to the prince's young age and inexperience. A brief civil war was instigated by Separatist commander Riff Tamson, Kolina's murderer, after which Lee-Char was crowned the eighty-third King of Mon Cala.

Imperial Era
Following the rise of the Galactic Empire, Char's government became influenced by a mysterious Jedi named Ferren Barr, who inspired them to refuse the Empires harsh terms. The Empire sent Moff Wilhuff Tarkin on the Sovereign to negotiate with King Lee-Char. Tarkin sent Ambassador Telvar to discuss with Lee-Char and he was unsuccessful. Investigating the possible involvement of a Jedi, Darth Vader and three Inquisitors arrived to find Barr and Lee-Char notified Barr of this. Telvar's shuttle was sabotaged and destroyed, killing all on board. Tarkin saw this as an act of rebellion and sent forces down.

The Empire began subjugating Mon Cala. The Mon Calamari retaliated by converting their buildings and civilian starships into warships and dispatching them from Mon Cala. Many of these ships became part of the Alliance to Restore the Republic and were used throughout the Galactic Civil War.

During the early rebellion against the Galactic Empire, Mon Cala was listed as an Alliance safe world despite the Imperial occupation. It was included in a map of the galaxy with a legend listing the various Alliance safe worlds, starfighter hubs at level five or higher, rebel operations sectors and regional headquarters, and shadow planets with deep space caches. The map was later incorporated into The Rebel Files.

Mon Cala was one of the worlds Emperor Palpatine intended to target following the completion of the second Death Star, which he planned to use to destroy the rebel stronghold and wipe out the Rebellion through sheer terror.

Skywalker's dream
In Luke Skywalker's dream in 34 ABY on Ahch-To, in which he imagined how things were if he hadn't joined the Rebel Alliance and instead stayed on Tatooine and married Camie Marstrap, the Empire used the Death Star to not only destroy Alderaan, but also Mon Cala and Chandrila.
