Scepter of Sarterus

A 3 foot long gray scepter, perfectly smooth and cold to the touch. At the top is an ornate hollow sphere made from incredibly thin metal. Despite the thinness of the walls of the sphere, it is very rigid. It is weighty, but not so much so as to be difficult to hold or point with one hand. It is capable of casting a command spell at a large number of targets. However, there does not appear to be a way to attune to it in a traditional sense.
