Samira Black

Samira Black was a notorious train robber during the early years of Ninjago. Somehow, she was the mother of Joseph but mysteriously disappeared not long after. According to Morro, she'd been murdered by her Sisterhood for having a child and her son was thrown into the split between continents when Ninjago was divided. Her soul ended up in the Cursed Realm, and as of now it's unknown if she went down with the Preeminent or she escaped like Clouse.
