For those that don't read CVRPG (shame on you), Righteous Heretics is the sometimes cameo-ing band that started in Comic 83. Shaft tried to take over the band, eventually, and it was this whole big thing.

Really, go read those comics so I don't have to explain it further.
 
    

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.
