World building: When a child is born, they're given a card that has the name of their power, and the rank of power for that power. The numbers vary for each power, but the number usually goes from 1-5. 

Prompt: Two twins are born, both with strange powers. One has two cards (Main character A), and the other has a card with the power number six (Main character B). The parents don't really care, but they don't brag about it either, so the twins go through the early stages of their life fairly early. 

Notes: For me, A was a boy and B was a girl. B had the power of telekinesis and levity. Levity was a rare power that made the user float, but it also had the side effect of making the user light-hearted and cheery. I made B very serious and emotionless when he wasn't floating, and I always thought that was a nice contrast. Telekinesis was called "advanced interpretation" and hadn't ever been seen before. A had the power of strength, which meant she had super, super strength, as the power number made the power increase exponentially. I didn't really have a plot, they were just characters.
