We all know of the Rubric of Ahriman, and the brothers of the Thousands Sons being turned to dust if they had little or no psychic powers, but what of their entombed brethren in the Dreadnaughts?
Did they retain their bodies and autonomy as 'living' Thousand Sons, or were they reduced to dust and remain silent like their Rubric Marine counter-parts?
And if the latter is true, would they still need a Sorcerer to lead them effectively?
This is all fluff talk, no game mechanics and such. Feed-back would be appreciated. Thanks.
