Bloodstone

She was formulated in a lab and was basically made of a Ruby and Green Chalcedony gem in a successful type of forced fusion. However she doesn’t have any previous memories of either side, [though the Green Chalcedony of her hadnt actually formed out of her gem, so ig you could say its mostly on her Ruby side she might have possible memories from]. In fact the Peridot on the ship with her is one that helped with her creation and is currently in charge of marking down progress and how she is acting reporting any mishaps or abilities found

She is quiet and more so just observes her surroundings before doing anything or saying anything, however she isn’t emotionless she just has a very tough time processing emotions and working with them.
Technically bloodstone can be a bit Naive but she has a fairly stoic demeanor most of the time that can throw off people of how she really is
