Background info[edit]

A Svarog Heavy Industries FF-ALPHA model fire management and emergency response doll. Designed in the mid-2050s, she can resists smoke, dust, fire and high temperatures and uses various firefighting equipment like a high pressure water lance, powder extinguishers and foam extinguishers. She was dispatched by Svarog for Project Neural Cloud in 2058.[1]

The FF-Alpha was released in early 2057 and started being used by governments by the end of that year. Aside from their robust hardware, they excel in real-time environmental data collection and analysis, while earlier Dolls couldn't do both at the same time. Chelsea was in the first batch of FF-Alphas enrolled in the Baltimore Fire Department and she earned an honorary award from the city in her first year, quickly leading to her selection for Project Neural Cloud.
