I think the Soul Drinkers could possibly be the remnants of one of the lost legions. My evidence: 1. Active at the time of the Horus Heresy 2. Considered rogue due to empathy to mankind and desire to have a truly free worship of the goodness of man and the Emperor (may explain their mutation allowing them to see a dead individuals memories and feelings, may be a result of their Primarchs genome like the Wolves fangs and eyes) 3. The Soul Spear is gene coded to a Primarch who is not Rogal Dorn, the supposed Primarch of the Soul Drinkers. The fact that Sarpadon the Soul Drinker Chapter master can use it implies that the weapon did belong to the chapters Primarch Based on this evidence, the Soul Drinkers may have initially folded the remnants of their Chapter into the Imperial Fists following either the destruction of their Legion in some action either against an outside threat or due to a rebellion they enacted, and their records were censured to hide the destruction of their legion and/or Primarch for fear of either acknowledging that their are more powerful threats then the Imperium could face without loss or to cover up the rebellion of an human-empathic legion that sought to truly provide freedom to humanity.
