Every assumption you have about magical rivalries is wrong. Vampires and Werewolves hunt together, Pegasi and Griffon fly the skies wing to wing, Dragons and Pixies inhabit the same castle ruins
All magical creatures live in harmony, except for Mermaids and Faeries. They've been divided for millennia
Young and naive Eclipse believes that all Mermaids are evil whores, stopping at nothing to lure sailors into the sea with their appealing bodies and beautiful siren songs
Young and optimistic Nadia is willing to give any magical creature a chance, even Faeries, with their scary wings and hateful personalities
When Eclipse gets into a slippery situation with a Hippocampus and Nadia saves her, Eclipses beliefs are challenged as she starts to become friends, or even more, with the optimistic fish, and Nadia starts to realize that Faeries aren't that scary, some are even quite beautiful.
