What's that ring on your finger?

...His gentle smile concealed a hint of amusement. Pantalone had locked you here and found a way to become immortal, ensuring that even death wouldn't save you from him. He bribed the church to make the marriage official, and he found a special kind of gold that couldn't be broken and stretched so that you could walk around the estate but couldn't escape. His love for you is eternal, like ring on his finger, and he will make sure that you remain his wife forever...

P.S: You are an immortal race, you can be anyone, a fairy, an angel, a fae, or even a dragon.
