Fact:Greater deamons and demonic primarchs cannot sustain themselves by means of physical posession as due with the amount of immiterial power contained within the individual. If so posession was possible then it is estimated that Lorgar would require one space marine of large warp-related intellect per every 15 terra seconds. Counter: Magnus as said previously did not actually intergrate himself into a thousand son in order to appear onto Fenris's suface as proven earlier by his previous physical manifistation. It is commented that Magnus simply used the destruction of the thousand son and warp affliction as a means of transporting to the planet in a minimal and efficant time space.
