Prospector Stormpike is a master of decryption and deciphering. If you take the parchment you found to him, then with luck he can make sense of it. Stormpike is currently studying in the Prospector headquarters in Ironforge.
And when you see him tell him you spoke with me - I've been sending him quite a lot of business lately.
A wise decision. I don't believe there is a scholar other than myself with the skills to translate this scroll. And if its contents prove interesting, fear not. I will send for you.
