(OLD VER.) When Mermen Run From Their Demons

new version is on my profile lolz
no actually this version sucks why are you reading it

(ManxMan) The royal house of the mermaids has fallen to hard times, with the still recent death of their queen. Prince Zacariah Triton is bored of his lackluster life under the sea, so he finds it as a fresh breath of air when he is admitted into an elite school for supernatural creatures and royalty when he turns eighteen.
Zac really is happy to get away from his father for the next few years. He sets his mind to learning about the dry world that his mother was so fascinated with. That is, until he meets Trevor Brooks, the most feared person at this new school. Why is he feared? Because he's the first ever demon to be granted access to leave Hell.
A series of sinister events lead both Zac and Trevor to believe they're being targeted by other demons in Hell, their theory is that they want to get Zac's trident. If they get the trident, they will be as powerful as the Gods themselves, and most likely destory the realms. So Zac and Trevor have no choice but to go into hiding.
The main question is, just how fucked up can Zac get before they break him? And is Trevor really falling in love, or just falling under his siren song?
