Blade #2

The queen of the Tryks is interested in a ceremony which will make Blade her king and an organization called the Seven is introduced which strives after a policy of 'vampiric equilibrium'. They kill both vampires and the Tryks which prey upon them, but only enough to regulate the numbers of both types. They are upset with Blade's recent escalation of vampire killings, as they don't want an all-out war spilling over into the streets, so they authorize assassinating him.
