Hunting Involvium: The Right Path!

Ha! I must be on the right path... I dropped down to the island I found (see the last post - it looks like an ancient volcano complete with mini-lake on the old caldera) and headed over to the first of the small wooden huts I saw. Inside, on a table by the far wall, I found these sketched plans... compare them to one of JS's latest posts and tell me I'm not on the trail to finding out more about Involvium!
