So, I just realised something thanks to a friend reminding me of a small fact.

Drukhari physically cannot be psykers. Their psychich abilities have massively atrophied to the point where they cannot tap into the warp to ues psychic abiities. There is not a single eldar alive in Commoragh that has psychich talents, so how by Slaneesh's third nippled scrotum does Lesara manage it? Also, and not to beat this point to death, I understand that they're willing to associate with Mon'Keigh, but why are they willing to associate with people who [i]actively worship the deity that would quite like to destroy their immortal souls?[/i]
