During Legion I think was the first time it came out that Gramaticus died & was then resurected by the Eldar of the Cabal n& made into a Perpetual, Then the Cabal resurected him again after the events of Unremembered Empire. Given The Alpha Legions capabilities they could easily have discovered how this was done at some point during the several years that the Alpha's & the Cabal were allied.
