So after I'm done with Control this week, I'm thinking of going back and reading all the original Section 31 books that I missed. I'm assuming that they are all part of the current litverse canon?
I know that three of them are. DS9: Abyss was part of the Relaunch continuity; TNG: Rogue was the debut of Ranul Keru and has been referenced elsewhere; and I referenced TOS: Cloak myself in Ex Machina. But I can't think of anything that's referenced VGR: Shadow.
