I read in another conversarion that the fallen may not be the traitors to the emperor, but that the dark angels where the real corrupted angels and that was the reason why they hunt the "fallen", so this give an idea of a chapter of fallen angels who are actually loyal to the emperor.
I haven't put everything together, as I'm still doing some research, so I want to ask the community, what would the fallen be like if they where to make a chapter to face the dark angels?
My thoughts are that this Guys have been pursued by the DA for so long that they are tired of this, so began to gather other fallen angels and star waging war against the DA. Some kind of dark angels hunters. Eventually, they learned that Lion El'Jonson is still alive, but dormant hidden in the rock, but they would believe that the the DA have kept him sleep for fear of him telling the whole truth.
Also, I have the idea of including the watchers in the dark into this "chapter", probably this little fellas decided to tell the DA hunters that the primarch was still alive and provided help in the difficult task that would be rescuing him. Probably the Watchers are the ones who gathered the remaining "loyal fallen" (as I think this DA hunters identify themselves) and are aiding in this taks. Probably I would use some allies, especially to represent the watchers in the dark in a way that truly impacts the game?
So my questions are.
1: What do you think of this background for a "chapter"?
2: what codex could work better, CSM, SM, DA or BA?
3: what rules could be used for the watchers in the dark? Inquisidor with retinue? Chaos deamons? IG psykers? Grey knights?
4: finnaly, what would be a good name for the chapter? Dark Angels Hunters? Light Angels? Brigth Angels? Pink Angels? Fallen Angels? Or just "The fallen"?
I want to make this army, so I plan to use dark angels miniatures, but do something with the Simbols, to make it look as if they scratched them regecting what the chapter has become. I would use mostly terminators, power armour infantry and bikes.
Thaks a lot. By the way, im mexican, so forgive my butchered english
