You visit Topaz two days later. "Time's up" she says.
Instantly you see a purple ring around you. After that you find yourself in Atlantis. "Uh-oh" you say, noting you can speak breathe and see perfectly fine underwater. "That's right!" Topaz says.
"I was about to return--" you start to say.
Topaz interrupts: "Mermaids can detect lies."
You feel the change beginning. You feel you're bones soften and turn into a mermaid tail shape before hardening back up. The tail then becomes lined with purple scales. Now comes the tg part. You're arms become hairless, thinner, more nimble, feminine at most. You're face gains a more feminine structure. "This feels weird." You say, but you're voice has changed. You lose you're light stubble along with you're Adam's apple and chest hair. You're body comes together and you're hip size increases. You grow a pair of perfect B cups. Finally you feel you're brown hair grow down to you're waist, and notice it turned blonde.
