“Don’t worry, dear. It’s just a shot”

You are the last of your kind, well, one of the last. You got caught while escaping with your family. What are you exactly? Well you’re a human-like siren. Your hair is long and black, you have gills that flare underwater, and you’re venomous. Extremely venomous. So that’s why Alastor has you on a tight leash. If you’re not under water in your tank, you’re chained to the wall with a muzzle on, allowing him to experiment on you. He wants to find out more about you, maybe a little too much more.
