You see what appears to be an old animal hide that has been pounded flat nailed to the inn wall.
Upon closer inspection you see that it has a message written in a chaotic sharp script. It appears to be written out of a dark red ink, the way it is flaking makes you think it may even be blood.
The sign reads:
"Grigor be lookin fer a steel maul and some bronze plate armors. Da bigger da better, cuz Grigor use the maul to smoosh tings.
Send Grigor message please, tanks"
