After thinking it over, I decided I might as well write a proper synopsis.
This is a very, very traditional Western fantasy novel, with tons of worldbuilding and enough Western names to make anyone's head spin. The pacing is very slow, so it takes a fair amount of patience. Also, pay attention: there's a 1 in the title, because this is the first book!
There will be elves, and there will be dragons. They'll appear in the next book, which will be a standalone volume about the Primordial Forest.
One more thing: the transformation tag is literal, and it refers to the protagonist, though they don't get much screen time in the first half of this book. What?! You want to know if it's gender-bender yuri, gender-bender romance, single, or a mystery? Read to the end and you'll find out.
