Real History Behind the Adventure
Medicine Lake is a real volcanic area in Northern California shaped by thousands of years of geological activity. Obsidian found throughout the region was an important material for Indigenous peoples, who fashioned it into tools and projectile points and exchanged it across extensive trade networks. The history and archaeology woven into The Obsidian Secret are inspired by this real Northern California landscape.
From Grandpa Eli’s Journal
The obsidian tells a story, but not the one I expected. The source is wrong for where it was found. Someone carried it here…or wanted it to be found.
— Journal 18, Eli Carson
