Dragon Sovereign And His Fae Captive

My mother had told me a story about a war that happened on Earth between realms eight hundred years ago. According to her, this war broke out because the dragons, being the strongest, wanted to be the ruling realm across the whole earth, and the other species refused to be under them. The dragons being so destructive was bound to destroy every other species that were against them ruling, be it lycans, werewolves, vampires, humans, faes, elves, griffins, and many others. But the goddess mother of the fae sealed the Dragon Sovereign, who was the mightiest of the dragons, the oldest among species, under the ground. Since then, dragons have stopped existing on Earth. A year after the war, my clan was prosecuted for a traitorous act against the fae realm, and were being executed every four weeks, until now that my brother was the only one they thought remained in the clan, then there was the powerless me whom they don't know about and could never save herself from danger, regardless, I was a fae. Now I'm in a dilemma while trying to save my brother from being slaughtered, and this is because I awakened the Dragon Sovereign who had been sealed under the ground for eight hundred years. This book is dark. It contains torture, explicit chapters (not from the beginning), and some other triggers. Beware, dear reader!
