1) There wasn't actually a set limit set on Inquisitors, it was more of a notional one, considering canonical cabals vary in size depending on the availability of Inquisitors and their own commitments.

2) There was no set limit on the number of planets created as this has grown beyond just an Inquisitorial Cabal and aims to provide as much creative freedom as possible. A sub-sector contains between 2 and 8 systems. This sector covers several sub-sectors.

3) Yeah, you're right there 40k. That's the main limiting factor: that all articles directly linked to the collab have to have been created specifically for it.
