New details about the planets and characters have been posted on the official Star Wars Databank. During SWCE, Gareth Edwards revealed that the planet Jedha was important for people who believed in the Force, it was like a holy place, the databank gives a lot more of information about it!
Jedha
A small desert moon frosted by a permanent winter, Jedha is home to one of the first civilizations to explore the nature of the Force. At one time a world important to the Jedi Order, Jedha serves as a holy site for pilgrims from across the galaxy who seek spiritual guidance. Now, the Empire occupies Jedha, and a prolonged battle between Imperial forces and scattered Rebels carries on in the timeworn streets.
Scarif
The planet Scarif would be a beautiful tropical paradise if not for the presence of a major Imperial military installation. Scarif is the principal construction facility for the vast Imperial war machine. The world is enveloped in impenetrable deflector shields and is heavily defended.
U-Wing
A sturdy troop transport and gunship used by the Rebel Alliance, the U-wing starfighter is a well-armed swing-wing vessel that must penetrate heavy fire zones to deposit soldiers onto battlefields and then fly air support during dangerous missions against the Empire.
Bodhi Rook
A former Imperial pilot, Bodhi has strong piloting and technical skills that he will put to use for the Rebellion. Ever practical, but highly anxious, Bodhi must gather his courage to bring the battle to the Empire.
Chirrut Imwe
Deeply spiritual, Chirrut Îmwe believes all living things are connected through the Force. His sightless eyes do not prevent him from being a highly skilled warrior. Though he lacks Force abilities, this warrior monk has rigorously honed his body through intense physical and mental discipline.
Baze Malbus
The harsh reality of his Imperial-occupied home world has hardened Baze Malbus into a pragmatic soldier and a crack shot with his heavy repeater cannon. Baze has a bravado that provides a marked contrast to the spiritual centeredness of his best friend and moral compass, Chirrut Îmwe.
Jyn Erso
Putting behind a checkered past by lending her skills to a greater cause, Jyn Erso is impetuous, defiant, and eager to bring the battle to the Empire. Used to operating alone, she finds higher purpose by taking on a desperate mission for the Rebel Alliance.
K2-SO
A reprogrammed Imperial security droid now loyal to the Alliance, K-2SO is an alarming sight standing within a secret Rebel base. The pragmatic droid is an effective insertion agent, as he can blend in perfectly at Imperial installations and outposts.
Captain Cassian Andor
An accomplished Alliance Intelligence officer with combat field experience, Captain Cassian Andor commands respect from his Rebel troops with his ability to keep a cool head under fire and complete his missions with minimal resources.
Director Orson Krennic
As director of Advanced Weapons Research for the Imperial military, Orson Krennic is obsessed with the completion of the long-delayed Death Star project. A cruel but brilliant man, Krennic has staked his reputation on the delivery of the functional battle station to the Emperor.
AT-ACT Walker
A larger version of the standard combat AT-AT, the AT-ACT walker features a dedicated cargo bed for the transportation of heavy building materials or combat munitions. It was deployed at major Imperial construction projects, such as shipyards and sprawling research installations.
Imperial Death Troopers
The elite soldiers of Imperial Intelligence, Death Troopers are encased in specialized stormtrooper armor with a dark, ominous gleam. These soldiers serve as bodyguards and enforcers for Director Krennic, a highly placed officer within the Advanced Weapons Research division of the Empire.
Shoretroopers
Specialist stormtroopers stationed at the top secret Imperial military headquarters on Scarif, Shoretroopers patrol the beaches and bunkers of the planetary facility.
They also updated details about Saw Gerrera’s databank file:
Saw Gerrera
A battered veteran of the Clone Wars as well as the ongoing rebellion against the Empire, Saw Gerrera leads a band of Rebel extremists. Saw has lost much in his decades of combat, but occasional flashes of the charismatic and caring man he once was shine through his calloused exterior. Gerrera is bunkered on the ancient world of Jedha, coordinating a prolonged insurgency against the Imperial occupation. Saw’s ailing health has not withered his resolve to fight.
