The Starglass is an item in Dark Cloud 2 capable of reversing time to a point of great importance to the user. In the main storyline, Max and Monica purchase one from Starlight Temple 100 years in the future in order to travel back through time with Lin and prevent Crest's death. It is used at the ruins of the lighthouse in Balance Valley, the site of Crest's death at the hands of Gaspard and the Death Ark. However, their intervention is still not enough to prevent the death of the future great sage.
