Your story rings true... I do not entirely understand your motives, but if your business here in Duskwood involves ridding the forest of worgen in any number, then I can forgo understanding for results.
There is a mine to the south that has been overrun with worgen... They appeared out of nowhere, but from what we know, that is where they first were found.
Go about your business, but I would ask that if you find anything of import, you share it with me. We will accept any aid in our war against evil.
