Bblyns used to have a sister city (whose name has been extrapolated from a fragment of text in an unknown script and clumsily translated), Akns. It existed on a whole other peninsula, and formed a rough equilateral triangle with Bblyns and Torre'kan, with Akns as the peak of the triangle.
Then, the established clerical hierarchy, feeling restless under a relative renaissance of knowledge and magic, decided to expand its network, teleporting teams of clerics, fighters, and woodcutters into the deep stretches of the old Antolian Expanse, commanding them to establish a system of linked outposts and bring enlightenment to the heathens.
This worked for several decades, and the druids even succeeded in teaching some Akns how to live in harmony with the forest, singing trees down. But the inherent superiority of civilization and the unconscious devaluation of the Antolian angered the druids, who took steps.
The first sign that the forest does not want you is crop blight. Those areas so recently liberated of trees by fire and ax will wither. The Akns had their clerics fertilize the fields. Next, animals began attacking. The Akns undertook extermination campaigns.
