I follow not the true path of Tzeentch i follow my Primarch's original goals the quest and knowledge and understanding. and i wish to cure the rubricae to an extent

This is what Tzeentch wants you to think

:O MY GOD your right

The realization of his manipulation of you is part of his great plan too, you should act as if you didn't know this; but that reaction of yours has probably been foreseen as well... *smirk* So what is your "intention" now?

still to cure my fallen brothers to an extent so they recover their minds once more. My loyalty is to my legion

Yeah, of course... *mutter* Just as planned.

but still I believe that this crusade will unveil secrets in the Arcane and hopefully I believe it will uncover a power to cure the Rubricae

Why should we cure them? They are perfect meat shields soldiers now following every order to the point (maybe not too bright but still ) .

I want the way our legion once was able to think for themselves instead of being mindless automatons, you cannot deny my need to cure my legion

You can always find the blood ravens and get started on rebuilding your legion
