I'm not sure exactly what thou know about a Thakrian and Ranger treaty, since thou art neither. (Scratch that, I DO know. Thou know nothing about it.)
To my knowledge, the last treaty Thakria had with the Rangers guild was broken ages ago by Sajora. In the last few weeks, no treaty has passed my hand.
Written by my hand on the 14th of Cloudburst, in the year 1017.
