Dolgrath sorceror of the Alpha Legion

Dolgrath of the Alpha Legion began to make an appearance later in the Stygian Wars.  Attached to the 7th Hydra company under Lord Magwar, Dolgrath worked amongst the stealth teams of the 7th.  Before the heresy it is recorded that Dolgrath spent time with the thousand sons as part of a librarium exchange.  What is known is his skill with psychic powers tends more towards aiding stealth and assassination than it does with mass destruction, although the two are not mutually exclusive.  Dolgrath also appears to have entered into an accord with tzeentch, unusual amongst the Alpha Legion that tend to be undivided amongst the pantheon for loyalties.
