The Mon Calamari people are a humanoid, aquatic species with high-domed heads, webbed hands and large, goggle-like eyes. They hail from the oceans of Mon Cala, a planet they share with the Quarren. During the Clone Wars, differences between the two cultures were fanned by Separatist troublemakers to erupt in civil war. During the Galactic Civil War, the Mon Calamari were said to be the soul of the Rebel Alliance. The Empire pressed these gentle, amphibious people into war by subjugating their watery world. In retaliation, the Mon Calamari became one of the key species of the Rebellion, supplying badly needed warships to the outnumbered Alliance fleet.
Also known as Mon Calamari or Dac, Mon Cala is a a beautiful aquatic world filled with lush coral reefs and kelp forests bathed by the light of twin suns. It is home to the Mon Calamari and Quarren people. The two cultures have long clashed over their differences, but under the rule of the 82nd King of Mon Cala, Yos Kolina, these disputes were kept civil and respectful. His sudden assassination and the arrival of Separatist forces during the Clone Wars tipped the scales to civil war, with the Quarren staging an uprising against the Mon Calamari, backed by Confederacy forces and Karkaradon leader, Riff Tamson. It was up to the Jedi and Republic envoys to help young Prince Lee-Char, heir to the Mon Cala throne, restore peace to the planet.
A ravenous Karkarodon, Riff Tamson was a ruthless Separatist commander placed in charge of operations on the water world of Mon Cala. Count Dooku tasked him to disrupt the fragile peace between the Mon Calamari and the Quarren. Though present on the planet as a Separatist envoy, he secretly conspired with Quarren chieftain Nossor Ri to bring the Quarren into the war on the side of the Confederacy. Though Nossor believed he was doing what was best for his people, he had no idea of the true extent of Tamson's wicked plans.
The Confederacy of Independent Systems, also known as the Separatist Alliance, was a collection of star systems and corporate titans that left the Republic and fought for independence against the Republic’s clone armies and Jedi Knights. The charismatic former Jedi Count Dooku was the Alliance’s political leader, while its military power came from credits and assets donated by powerful galactic trade groups. No one suspected that the Alliance was actually a tool of Darth Sidious, who had engineered the Clone Wars as part of a Sith plot to rule the galaxy.
A veteran commander, Ackbar led the defense of his homeworld, Mon Cala, during the Clone Wars and then masterminded the rebel attack on the second Death Star at the Battle of Endor. Ackbar realized the rebels had been drawn into a trap at Endor, but adjusted, with his fleet buying valuable time for the attack to succeed. After the Battle of Endor, Ackbar became a Grand Admiral in the New Republic, winning many victories including the pivotal Battle of Jakku. He retired to Mon Cala, but was coaxed back into service with the Resistance by Leia Organa.
The chieftain of the Quarren people on Mon Cala, Nossor Ri was a friend to Mon Calamari King Yos Kolina, despite their clashing viewpoints. He was saddened by the shocking murder of the king, but could not support the rise of Prince Lee-Char, heir to the throne. Nossor believed Lee-Char was too young and inexperienced to lead the planet. Goaded by a Separatist "adviser," Riff Tamson, Nossor Ri called for new leadership, and a chance for a Quarren to hold the throne. The Quarren chieftain would come to regret siding with Tamson and the Separatists.
