Apparently, Alisha Valior wrote a duology...(if you've read Empire, you'll get the reference.)

Anyway, this set of two covers is available as a premade! If your series has more than two books, I'm happy to make more covers in a similar style. 

Here are the mockups for these books! They're my very first mockups, and I have no idea why they're tiny and/or blurry, so please don't judge! If you're wondering why they're facing a weird direction, it's so I wouldn't have to make spines xD
