You're getting close to the edge of TMI -- maybe over it. Concentrate on Taraseya, not the backstory/world-building.
Taraseya will end the war between Nephilim and Guardians
, . Ancient, immortal, and endowed with devastating powers, the sworn enemy races
have been locked in a standoff over control of the Earth for millennia. Taraseya is both Nephilim and Guardian, and more powerful than any member of either race. Her allegiance will determine control of this world, and all others, for all time. There is only one problem—
Twenty years after her mother the Queen of Laryial threw Taraseya from the cliffs—driven mad by her ensorcelled union with the Nephilim—
a strange force ripples through the universe. Way too vague, and you don't need it. You say it here --> Guardian and Nephilim are drawn to the Earth kingdom once more. To their mutual shock, they find that control of the Earth now rests with a penniless orphan living with the last gargoyle tribe.
Anaiiya is unaware of her true name or nature, and her life is thrown into chaos when each side demands she join their cause against the other. No matter which side she chooses, her adopted gargoyle family will suffer. When a trap is sprung forcing her to pledge her allegiance or watch her adopted gargoyle tribe die, Anaiiya must find a way to save the only family she has ever known, as well as the rest of the world, from her warring families.

My edits in the first paragraph leave it a bit choppy, but I think you get my drift.
You are soooooooo close!
