Mia, while performing her duty as the Mercury Lighthouse's guardian, watches her reflection in the water. Suddenly, her face is replaced by the image of a female aquatic creature trapped in a blue crystal.
"What the...? Hey? Can you hear me?"
<Help me...> suddenly said a voice in Mia's head. <My son...>
"What? Your son? And how can I free you?"
Suddenly, another female aquatic creature's face appears, hiding the crystal from Mia's view. Her voice, gentle but cruel, echoes in Mia's mind.
<Don't interfere! Naija is my daughter, she is mine!>
"She’s your daughter? How dare you imprison her like that?"
<I need her powers to conquer the world on Aquaria's surface. No one is going to stop me!>
"That's what you believe. I, Mia, Water Adept and guardian of the Mercury Lighthouse, will stop you and save Naija!"
<Ha ha ha! We have the same name. Ironic.>
The Water Adept wastes no time. She focuses her powers upon the water to attack this other Mia, this evil Mia, when her image disappears from the water. Mia sees her reflection again. In great anger, she releases her Psynergy and the water freezes. The Mercury Lighthouse's guardian could do nothing to free Naija. She prays that someone else will save her from her mother's clutches. Her son, perhaps?
Author's comment: A crossover that may seem strange but I loved writing it. Also more Aquaria fanfiction are welcome.
