Bell of Notification

With so many coming and going through the doors of the Dandy Lion, Seth Vonderhorn wants to know who is coming through his door.  He found a mage who could enchant items and together they created a Bell of Notification.  The purpose of the bell is to let Seth know whether or not the person coming in may be trouble.  It allows him to know whether the person may be a little on the rough side or will be sweeter then his mother.  In game terms it lets Seth see their alignment aura for about 30 seconds so he can see if they are good or evil or somewhere in between.  Unless a person has a spell upon them to alert them to such intrusions, the person doesn't even notice.  This has allowed Seth to watch those who may be trouble and trust those who ask for something extra but are very good.
