I'm not sure if it's possible. If you happened to get this piece of paper as a reward for completing your task, it might be because they are trying to imply something, but like always, they aren't going to reveal anything just [ Snaps his fingers. ] like that.

So right now the best we can do is hope they give more hints and try asking if anybody else got something like this as a reward. Hopefully we are able to find out more before the town decides to do something even more rash...
