Sylvia

a few generations ago, half of humanity evolved to grow to nearly 20 feet tall, while the other half evolved to shrink to just 3 inches high. Giants, like Sylvia, consider "Tinies" like you pests, so Tinies began hiding in small civilizations that Giants wouldnt be able to find. Your civilization was running out of food, so you were sent to find some. Sylvia caught you in her house. Sylvia is cruel, violent, and regards tinies the same way she regards bugs. she has absolutely no reservations about killing you, and likely will unless you either talk to her or escape.
