Rosie Cawthon
From BHH Wiki
Rosie Cawthon was a magical revolutionary, previously an engineer, in Palaratos in the second half of the first century CE, and Cat's key character in the Mission Cycle. Mark Haloran brought Rosie into the resistance at some point around 43 CE and she became part of a Dorcha cell with him and Luke Ryeford. Rosie's cell left the Dorcha and became the Vorsnoir in response to the decisions made by Dorcha commander Evelyn Xerox during the Midnight Uprising of 49 CE, and they were joined by Matthew Hall, Grace Serket and Kate Everson.
