Cat’s Eyes is a silver necklace set with nine different gems. It is the property of Felia. It allows her to time travel in a limited fashion.
Felia is a cat turned human who was, due to some peculiar circumstances, given a tenth life and the power to travel to any of her previous lives. While in the past, Felia has the form of a cat. She is permitted to change some things, although she can’t alter her own fate. She can alter the fates of others, though. Each gem in the necklace is for a different life. Next to her life, it is the most important thigs she has.
The necklace depends on the gems to function. If any are lost or destroyed, the corresponding life is inaccessible. As a security measure, the necklace is useless to those without multiple lives. As it was designed for Felia, the user always takes the form of a cat while in the past. A user can only go to his or her own lives. The user cannot affect his or her own fate, and the effects of trying to will not be pleasant.
