Universe/Fandom: Unicorns of Alnilam
Prompt: 051. Water
Artist's Notes: Those who have been the victim of almost drowning tell stories of a creature rescuing them by pushing them to the surface and guiding them to shore, although none can confirm this, for whenever they turn to thank their savior, it has once again vanished beneath the waves.
Atlantis is a mernicorn (mermaid-unicorn). She was created, I believe, back when I was around 14 years old.
