I thought I should complete the sciences trifecta and make some biological characters
I've always had a fondness for "people get shrunk and explore inside someone else's body" storylines because of the fun ways people re-imagine the inside of the human body
I've had various ideas for my take on this trope but I'm going to start here with this silly critter I'm calling an "animalcule" (which is an archaic word for various microscopic animals - in this universe a plant cell would be called a plantacule, fungal cell is fungicule, etc. unicellular organisms are just referred to by their actual names. all these are collectively referred to as "cellfolk"). This one is a keratinocyte. I'm tentatively calling it 'Kera'. Kera gets lost inside the Self (the body it lives in) when a puncture wound from Outside causes it to get swept away in the blood. It manages to avoid the fate that usually befalls a keratinocyte and goes on wacky adventures with various other animalcules within the Self.
