Maple is the tom cat. He loved Lunar since he first met her. But they got caught in the middle of a human war. But one day a human dropped a nuke. When Maple and Lunar were running lunar got stuck in a fox trap and was killed by the nuke. After that terrible day Maple blamed himself for her death. Until Lunar visited him in his sleep and told him it wasn't his fault, it was the fault of the humans. When Maple saw Lunar start to fade away he begged her not to go. Lunar told him that he must just let her go.
