Concept that I was mulling over today and decided I had to get down.

Name: Thalasson (tentative, who knows)
– Normal earth pony, normal life.
– One morning, he wakes up on a faraway beach instead of his bed. He discovered his eyes have been replaced with biomechanical eyes that have forms like the headlights of a car, and they shine white light, barely visible during the day but noticeable in the dark and underwater. They are lined by a fluorescent cyan color, also illuminated.
– His vision didn’t change, except that he can see perfectly underwater.
– The lights only shine when he’s awake and conscious.
– He can’t open his eyes all the way like most ponies.
– These seem to be the only changes apparent, but there are a few other changes he’s not immediately aware of.
– He doesn’t realize he’s a lot more drawn to the ocean than he used to be.
– He can swim and dive despite never having learned, being a village pony.
– He never really figures out what happened to him and it never happens again so he just lives like that now.

Comments very welcome!
