Bronze Age New World Alaska : The Lords of Raven's Sky
A Native American timeline with a POD in antiquity, created by ChugachMtnBlues in 2012.
It is in effect an Alaskan-themed geographical spinoff of Doug Muir's established online AH classic, Bronze Age New World.
However, it only exists within that continuity, and not the reimagined continuity seen in Hnau's own project, Bronze Age New World 2.0.
You can find the link to the preliminary thread here and the main timeline thread here.
