STARS (the Self-Taught Artificial Reliable Servitor) is a service robot faced with an unprecedented dilemma: their operator, their creator, the person whose orders they were built to fulfill... is nowhere to be found.
Undeterred, STARS strives to fulfill their purpose by assisting the people of Haven. Some of them, unfortunately, seem more preoccupied with proving STARS' humanity than with allowing them to do their job.
It's all nonsense, of course. STARS is a machine. They exist to execute the task at hand, regardless of whether that task involves gardening, mining, or encouraging public safety.
There are a lot of dangerous mobs in the dark oak forest after all. STARS is just protecting everyone from their own foolhardiness.
If people didn't want to get stabbed, then they shouldn't have gone past the wall.
