I, for one, am dying to play a Cognitae trained mastermind in the vein of Zygmunt Molotch.
I think there was an attempt to create a secret training school somewhat similar to the Cognitae in the Radical's Handbook, but the name of it currently escapes me. I think it was a background package.
A true Cognitae character would be cool, though. And the Cognitae are known in the Scarus Sector, which is fairly close to the apparent setting for Black Crusade on the border between the Calixis Sector and the Koronus Expanse.
