Another Artifact Medallion and More Knowledge

After further exploring the demonic vault, me and Tara found another artifact medallion but no artifact weapons or armor. Also, we found a scroll on a pedestal. I read it, and it gave me the knowledge on how to create some new powerful weapons. I also examined part of a demon wing that was on the ground. I was thinking of bringing it back as a trophy, but then I said no. Now, we're just about to leave the vault and head back to Chilliwack.
