You can choose which will be easier for you. I had originally wanted it to resemble the saga back of the card. Here's the story from the guide. You may edit out parts for length:
Jango fett's background and exploits are mired in legend, with few verifiable facts-perhaps by design.
Oe such story: As a boy, Jango was orphaned when his family was caught in the cross fire between the terrifying Mandalorian Warriors and their rivals, the Death Watch, on the planet Concord Dawn. A sympathetic Mandalorian commander named Jaster Mereel took pity on Jango and made him a cadet. Soon he was traveling with the nomadic army-for-hire as they toured the galaxy looking for conflict, always in the service of the highest bidder. Over time, Jango rose through the ranks. When Jaster Mereel was killed in battle, Jango was named commander, the youngest in the long history of the notorious mercenary army.
Since ancient times, Mandalorians were brutally effective fighters, and especially so under Jango Fett's leadership. However, while fighting to suppress a popular revolt in the Galidraan system, the Mandalorians ran afoul of the Jedi Knights, who wiped out most of the mercenary army and delivered the survivors to the governor of Galidraan. Jango became a slave, but he used the next several years to regain his strength and plot his eventual escape. He exacted revenge on his captors, reclaimed his Mandalorian armor and set off on his own as a Bounty Hunter.
Armed with dual blasters, a missile-equipped jetpack, and a host of other deadly tools of the trade, Jango Fett is now among the most feared bounty hunters in the galaxy.
