Percy Jackson & The Olympians livres
Riptide is a sword of waves given to Percy by Chiron. It will return to his pocket in pen form when lost. The pen can be uncapped when needed as a weapon. It is a meter long and made from celestial bronze. Celestial bronze is a nestle that is mined from mount Olympus, it will not harm pure mortals only Greek things. The sword has a troubled past but apparently according to Sumabrander (Jack) it is a hot lady sword!
