Sierra is a run of the mill VE11-S42 Mechanidroid. She was bought off the production line by the organization that owns Station IOWR351-MS and was shipped there when the station was first built and then kept in storage until she was brought on to the crew 20 years ago when they were having trouble hiring and retaining a flight engineer because of the station being so derelict, out of the way, and uninteresting to work at. She is kept on staff to keep track of the station's orbit and flight as well as be ready to pilot if that was ever needed. Since that's not a very demanding job and it's such a small station, she also does most of the station maintence and cleaning.

Current Story

When Meredith joins the station, Sierra was at first unimpressed and also felt somewhat territorial of her spot as 'the robot' on the station. Meredith makes an effort to reach out to Sierra despite this, and they grow closer. Sierra and Meredith discuss issues of robotics, artificial intelligence, and androids and Sierra isn't accustomed to thinking about such things but enjoys the chance to engage in deeper conversation with someone who wants to hear her thoughts. She's used to being condescended to by Clara and seen as friendly enough by Robin but they don't have the type of friendship that solicits deep conversation and thoughts about life and the universe. Meredith discusses her dream with Sierra, also admitting that she got into robotics for that and hasn't had a lot of interactions with AI outside of things pertaining to reaching her goal and so finds Sierra's company and conversation enlightening and perhaps even leading her to rethink her plans and the way she regards robotics and AI and seeing them as something valid unto their own existence rather than simply a tool for human usage.
