The griffin is immortal.

Near the red tent, all the keyholders are located in the territory of Markel.

I approach these vampires, and nothing happens. Is there a condition that needs to be met for the script to trigger? Maybe you need to have 100 crystals at once. Because I've approached them several times. Not only can't I "click" on them, but they also don't react. By the way, I also have another quest pending. "Suppressing the Rebellion," will it be completed later? Because I thought this quest would be completed after destroying the blue one.
