This is Brook. Her sister, Stream, was the leader of the group. This was all fine and good, until she started suggesting ideas. Her sister almost never acknowledged them, and when she did, she'd either mock her ideas saying how dumb they were, or steal it as her own, then boast about how 'she' came up with it and her sister never had any ideas. Eventually, Brook came out and tried to reveal her sister as the corrupt cat she was. Some wanted to believe her, others openly rebuked her. Stream came out while she was revealing her evil, and declared her as a lair, claiming she was all making this up to get to the top. Stream exiled Brook and all of her close followers to the dark forest around their homes. Brook met a mage who taught her black magic, which she fueled with her hatred. Ever since then, she's been trying to get back the territories with her new army.
Uh yeah so I did this for fun
