Piper

The Piper is one of the Star Signs of the Old World. It is the Sign of the Trickster, appearing as a capering piper, and is in Ascendance during Autumn. People born under it are known to be diplomatic, cunning, and shady.

Overview
The sign of The Piper has always been regarded with some suspicion. Astrologers believe great leaders are born under this sign but also great traitors as well. Some even believe they are one and the same. Characters born under The Piper tend to be willing to negotiate in most situations, trying to look for a happy medium. But these characters also negotiate deals at any cost, even playing the two sides against each other or tricking one side to achieve the desired goal.
