Let's see what the mailbag has for us today! This first letter comes from "S in Askr."
"I'm a member of a certain...heroic order. I serve under a commander who has an obsession with money, leaving me with lingering doubts about her priorities.
"I think I'd feel more at ease if we could bring in some more powerful Heroes to keep the order strong. Please, help me find some Heroes that would be immediate assets to the team!"
...Nice try, Sharena, but you could have been a bit more secretive about your identity.
Heh heh! Sorry, I just thought that recruiting some strong Heroes would make everyone's lives easier—yours especially. So, do you have any leads?
Immediate assets... In other words, Heroes that are fighting fit and ready to go? Well, I have an inkling...but I'm not convinced by your excuse for that letter of yours.
