The letter is written in a rough style, purely in Orcish runes. The runes appear to have been inked on with a claw, rather than a quill.

Graahk, Cave Mother.

It has been too long since we last stood side by side and made war upon the lesser races. I have made a call to all of our kin I can find, and hope most will respond. The Tribe is in its infancy, but may be beginning to form into a true force. But you Graahk, were my most promising warrior. And Cave Mother, your guidance and assistance will be required to care for the Tribe and ensure its continuance. Contact me at what was once Dunedar Hall in the Canal Ward, and we shall meet as soon as possible.
