I'm not a 40k expert by any means, just a longtime fan. I've neither heard of, nor been able to find any information on this Chapter. Now for the feedback... The inquisition already has a host of Chapters tied to them, not the least of which are the Grey Knights and I would assume by extension the Excorsists, as well as the Black Templar, Adeptus Sororitas and even the Deathwatch should they feel like it. Do they really need yet another secret founding specifically for the issues in the sector? Personally, I'd just as soon see the local SM representative fleshed out through one of the existing chapters that are well known ( even if semi-secret in some cases ) to work alongside the Inquisition.
