Mysterious Realms: Revak Feykro [Rewriting]

This is an old version of this story I started in 2015. As of now, April 2018, I have a few working chapters. Hardly any of the information given here is the same, but general information will mostly be kept, along with characters and personalities (though some personalities will change to be more realistic). Please enjoy this first attempt of mine.

This book is being rewritten, but the same idea will be kept. Just stretched out a bit.

That same psychic, however, also saw a future where those chosen die, and Dark Wings falls. Nothing is immortal but memory, and those chosen might just become one; a memory.

The chosen are not born, nor hatched, yet. Before everything, Myrkr and Sanguine, two Revak Feykro teens, are sent behind enemy lines as recruits. Myrkr learns what she is, and Sanguine does what he's supposed to while his companion does research, which turns into an obsession in his eyes. The duo make friends and gain the information they need, but will they both go back home in one piece after a third party joins the fray and steals something cruci
