Drystan was a normal human, so how did HD know a hybrid merman like you? Well it was a long story.

You were on the beach, no idea anymore how you got there, yet dried out by the hot sun and burned.

Drystan had found you just in time and got you quickly to his house. Now you were in his bathtub, filled with water and your tail slightly sticking out.

You were a bit better, but far from okay.
