Stalk about the shadows like the rogue I am. In the black mass, around the black mass, under the black mass, I'll make the black mass my hoe. Then I'll scrounge around for survivors and noms. If there aren't enough noms, I'll "reduce" the party to accommodate. Then I'll probably make my way to the speakers and play Epic Sax Walrus.
Then I'll return to stalking. Possibly some brooding.
I am extraordinarily stealthy without meaning to be. Several times I swear I've made quite a racket, talked to someone next to me, and have them jump and say that I gave them a heart attack. I have a natural stealth aura.
