i'm not sure how emps' prohibition on psykers invalidates entry to this list - pretty sure it wasn't emps who started this thread :P, but ok.

but if that's the case then that automatically voids mephiston from this list, most blood ravens, and anyone with psychic abilities.

i think neithan means that erebus' psychic abilities are directly bestowed by the gods. unlike ahriman erebus wasn't a psyker to begin with and didn't learn his abilities, they were a 'gift' for his devotion. ahriman is a natural psyker (or as natural as you can get with genetically engineered supersoldiers :P), while erebus is a chaos psyker.
