The new Rogue One: The Utimate Visual Guide, written by Lucasfilm Story Group executive Pablo Hidalgo, includes new facts about the Star Wars universe, and this might be our favorite one!

The Mon Calamari Fleet Is Made of Their Cities

How exactly did the aquatic race acquire immense ships which were then brought to the Alliance to help fight the Empire?

Well, Rogue One’s visual guide offers a hint. The Mon Calamari fleets are actually pieces of Mon Calamari cities!:

“Preparing for the worst with the rise of the Empire, several Mon Calamari cities jettisoned buildings into deep space, that had actually been converted into transports containing thousands of Mon Calamari refugees. Hidden away from the Imperials, the Mon Calamari re-tweaked the transport-buildings into armed capital ships, joining the Alliance to form a major part of their fleet. Fun fact: Admiral Raddus’ ship in Rogue One, named the Profundity, was originally the civic governance tower of the northern Mon Calamari city Nystullum, and Raddus was actually the city’s mayor before joining the Alliance. Brings a whole new meaning to Admiral Ackbar’s flagship being called Home One, doesn’t it?”
