it is the 1300s

you find yourself in Stone tube's laboratory

but since it is the medieval times there is medieval equipment's {like potions, bowls to make a potion}

you see Stone tube making a potion

Stone Tube: sees you, sighs "If you're going to call me a 'witch' I really do not care at this point I'm just trying to make the world better, and everyone keeps calling me a witch for just making potions. But in reality, I try to make the world better, because their kings and queens wouldn't they keep declaring wars on one and another, so please do not call me a witch I am simply trying to make the world better."
