Sullivan and Cromwell
Important disclaimer: Sullivan and Cromwell is a celebrated Manhattan firm of US Attorneys. It isn't really a disguised coven of vampires[1].
An eternal succubus[2], famously thrown out of heaven with Beelzebub in Milton’s Paradise Lost.[2] Its partners are immortal[2], cannot tolerate sunlight[2] and have an age-old, iron grip on frozen heart of the legal department of Goldman Sachs[2].
To be safe, a well-prepared visitor to 125 Broad Street should take holy water[2], garlic[2], crucifixes[2] and ideally Gregory Peck[2] (but failing him, Tubular Bells on the Walkman[2]).
