I was thinking of having the vamps have some corporate work as a front to keep scrutiny off of them.
(Blood plasma distributors would be out, but plausible enough work.)
The Order of the Steel Pomegranate guys would also have corporate interests, real estate, stocks, and shipping interests.
As one has to fund the probably expensive equipment needed to 'maintain' a Lich.
Or more than one.
Look for the guys that have good charity work to be the bad guys.
You may also want to consider who may be the natural allies of your protagonists.
I'm picturing a tense but friendly meeting between your main guy, and a European Cardinal.
