Intro. Summit is whatever age you think... she doesn't know. Her parents were lost—killed by natives on an archaeological dig. During the dig, they found a ring. Wearing the ring, Summit can summon a war tiger that aids her. She can ride the tiger, sleep on him, whatever, and it helps her hunt and fight. You found her because she is your relation. Her tiger isn't dangerous to her or people she deems safe. The tiger can appear or disappear into thin air on her command.
