The Pendant of Hyacinth

Prince Arael Kendall's past comes back to haunt him when the Nightmare Crisis throws his life into chaos. In a last ditch effort to make things right, he runs away from home and finds himself in the company of Hazel Redwood, a happy-go-lucky teen with their own secrets to sort out. As an odd string of coincidences begins to reveal the duo's missing pieces, the monsters called Nightmares continue to ravage the world to the west. 

After reuniting under the most unexpected circumstances, Thalia, Hazel, and Arael strike up a deal that results in all three returning to Eos. Hazel wants to remain in Fantasy and use their newfound abilities to help, but Arael has already promised to return them home safely. Thalia, defending Hazel's right to stay and desperate to cling to her chance to end the Nightmare Crisis for good, stands her ground and begins to train Hazel despite Arael's protest. However, the dispute digs up old wounds, and things end up more strained than ever before.
