The lives of demigods had cooled after the Giant war, and things had been starting to settle.
That, of course, was when the gods chose to drop a huge announcement that changed their lives, AGAIN.
Two demigods- one Roman, one Greek,- would be joined in marriage to signify the unification of the two aspects. These demigods would be the bridge between them, showing that they COULD be unified as one. Said demigods would have no choice in the matter, meaning they would be forced to marry one another no matter their personal lives.
Oh, and lastly, did they mention that the two demigods would be female?
No choice but to accept their fate, the two must find their own bridge of unity to be able to bring peace to their people.
Unfortunately, they have much less time than expected.
Enemies arise from far away places, growing slowly but surely in power and strength. The gods assumed the enemy would be easily conquered, yet they would soon be proven wrong. These beings...they held a power that was undefeatable. If they learn to wield this power, it could surely mean the end of all. But with every power comes another way, and the two female warriors must find that way before there is nothing left to defend.
