This "box" appears to be an acorn shell. When the shell is opened, a childlike chorus of pixie voices sounds from within it for the next six hours, drifting gently on the wind. At the end of that time, the pixie music stops, leaving only a plain, hollow acorn. While the music is sounding, natural beasts won't approach or attack anyone in the sound's area (a 20-square radius), heeding the pixies' beautiful song and staying away out of respect for those magical creatures. * Price: 50 GP
