This Comic's Cast:

And, as we can clearly see, Darkmoon has no charms of his own. He's quiet charmless. Charm deficient. A charm null.
This comic does go further into the dark gifts and how a vampire is animated and powered. The darkness (not the band) give a vampire it's "life" and powers. It's not demonic, as that's a different power-set. Plus, were it demonic, then a vampire would be evil, no choice in the matter. As Darkmoon demonstrated time and again, being a vampire didn't really change him much. He's clearly not some evil demon, unless the demon was as inept and lazy as Darkmoon was.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
