Dusk of the Falling Moon

I'm writing out a plot bunny, bear with me 😂

I thought we'd never see them again.
I thought, when they left, they'd never come back.
I, and everyone else on this continent, thought wrong.

It's been nearly a year. I don't know why they'd come back now. To torture us again? To kill even more of us than they did on that disastrous night?
The clans are hostile toward each other. They always have been. But now, we need to join together, and it needs to happen soon. Our lives are at stake.
And it is my job, and my clan's, to lead them. To fight these strange beings. To end this battle once and for all.
