A parcel came wrapped in plain brown paper. A padded box, carefully packed so that the two vials of translucent, black-tinged fluid within wouldn't be broken in transit. Addressed to Darsa. A note enclosed within, in a heavy, messy hand. "I remembered your research, the other day. I once used this substance to suppress my better nature. Of course, shortly after imbibing one I promptly needed to be able to find my fangs and claws, and couldn't. Perhaps they will be of more use to you." ~Thorn.
