Take the Fel Reaver Construction Manual to Mama Wheeler at the Midrealm Post inside Eco-Dome Midrealm in the Netherstorm.
- Unknown Objective (Provided)
Cracking the seal on this rather large tome, you can't quite make out what the words say. They appear to be written in the language of demons.
However, you can make out the pictures, which tell their own story.
This is clearly a fel reaver construction manual, and you know for a fact that Mama Wheeler will want to take a look at it!
