A timeline with a medieval divergence, set in the Arctic parts of the northern hemisphere and focusing mostly on native cultures of the North American Arctic, written by DValdron and DirtyCommie. You can read the timeline here. Alternatively, you can read it more easily with the help of the chapter guide available below.

The timeline concerns alternate advancements (mainly agricultural) among various Alaskan and Paleoasiatic peoples, primarily the historical Thule culture of early Inuits, triggered by ATL contact with the proto-agricultural Dena'ina hunter-gatherer culture from more southern latitudes of OTL Canada. It also covers how these native cultures, already advanced, but even more diversified thanks to the ATL developments, act once they come into contact with Europeans and Asians.
