Looks like Resistance Reborn and Allegiance will focus on The resistance trying to rebuild itself after the fleet was mostly destroyed in The Last Jedi.

Interesting that Allegiance focuses on the Mon Calamari. Both Marvel's ongoing and Vader series both focused on the Mon Calamari around the same time last year, with the Vader comic basically showing Raddus's faction escaping the planet, while the monthly one explained where the Rebels all got their fancy new Mon Cal ships in ROTJ.

....and of course your usual art and visual dictionary stuff.
