This is basically set up around the idea of a chapter made from a loyalist that managed to escape from the Traitor Legions. Having an ally from Ordo Malleus works in nicely since if you remember, the original Inquisition had 8 of its members from the Traitor Legions that stayed loyal. Eventually they would take a geneseed from one of them and make a new legion. Of course, in the middle of creating them, Guilliman dropped the Codex Astartes that kind of ran in the opposite direction of what they were going to do. Because of that, Ordo Malleus scraped the rest of the expansion, though not before they got some stuff. So they're essentially a half-made legion that got awkwardly reformed into a Chapter. Hereticus being suspicious sort of works since they're all about eliminating those traitors, and now Malleus has to run interference to protect their investments. And Hereticus managed to recruit a Chapter that's also about eliminating those traitors.
