I think you guys are being a bit unfair. I'm sure this would have a 4.25 rating if one of the older hands had put it forth.
As for myself, I think that it still needs some work in terms of additional plot hooks. We could all probably come up with a few good uses for this toxin (Wulfhere's already started!), so why not put a few forth. Flesh it out a bit. What exactly is a Howler Demon? Why should we be afraid of it? Do Demons reproduce sexually, and even have pheremones?
I could see a large problem with the respiratory and circulatory systems- the lungs and hearts of both animals would need to be enlarged to cope with a sudden increase in mass. Would the human head get too hot, as it's less efficient at shunting excess heat than its equine counterpart?
Otherwise, a very nice way of making a legendary creature more palatable and realistic. Good work. Go to Comment
A typical iron ore mine, the Irongate was closed some years ago and the entrance was closed off with a heavy gate of oak and thick iron bands, the Irongate. The mine itself was abandoned because it was a breeding ground for dire rats and many of the miners suffered from giant rodent bites as well as diseases from said bites. The mines are haunted by the ghosts of the men who died in dire rat swarms, adding to the mine's unpleasant character.
