From Mithras' point of view. Ancient Garou spirit eating his soul. He knows he can take over pretty much anyone who eats him...so Dominate + Presence lots "Diablerise me".

And I was good enough to pull it off in the face of all the competition.

Fundamentally, barring a lot of effort from me, my pack and various other people, and a hell of a lot of luck, I'm doomed to become Mithras. But it'll be a fun ride down to the end... :-)
