The Mandalorian Armor
Star Wars: Bounty Hunter Wars #1
2 stories. One taking place around New Hope and the second during Return of the Jedi.
First story is about Fett taking down the Bounty Hunters Guild.
The second story is what happens to him after being eaten by the Sarlacc.
Not really sure how canon this is, considering all that Traviss has written about the Mando and Fett himself. I’m enjoying it though. No jedi, lots of assassins and bounty hunters though.
Update-considering how Lucas has trashed Traviss’s Mando continuity, this is as canon as you want it to be.
