Ratulous is a rat and dog hybrid monster who frequently the Librarey (yes it's spelt like that) like it's a second home. She loves reading. She was visited by a mysterious man who told her every action she makes has significant rippling consequences on the world, she was also given a Shimmering Shard, but it broke and she's been trying to discover its secrets since then, but has had no luck. She is obsessed with trying to talk to the man again and get answers to her questions. She's witty.
