The unnamed Piper was the last Piper of Pirra before the Pirran Pipe was split in three. Pirra's undoing began after she died, as the people of Pirra could not decide upon the new Piper.
The Piper played the Pipe in Pirra, keeping away all evil. She passed away in her sleep, leaving the tough decision of a new Piper to the Pirrans. This ultimately allowed the Shadow Lord to trick the Pirrans into splitting the Pipe into three pieces, which allowed it to invade.
