Prologue:

Blood everywhere. The air stunk with the bodies of her allies and enemies. For a brief moment, for a short silence, she was able to catch her breath and sit down. The Shrine of Naga was shattered in pieces. Her grip gave way and her sword kissed the floor. The solid "clang" echoed throughout the main hall.

She looked around for any sign of life. Sanguine was all she could see. Her friends were far and her parents have passed on to another life. What hope is there left in her world?

"What would father do? What would mother do? Tales of their audacious battles and bravery tell me to never give up. Never give up even in the face of misery. Now that it is staring at me…"

A long sigh left her as she picked herself up. She held her sword firmly once more, ready for the next adversaries that would meet her. As she examined her sword, the ground shook and the skies revealed a gargantuan figure. Its wings were black as the darkest ink of night. Its blood-red eyes stared at Lucina as it let out a deafening roar.

Grima. The Fellblood Dragon that was put to slumber a millennia ago rose again. With the Fire Emblem lost and its most recent Exalt slain, little hope was left. The Awakening Ritual, which was meant to be the only weapon that can fight this deity, is now but a dream gone by. As a last resort, Lucina made her way to her private chambers and prayed to Naga for guidance. What more can a mere sword and child do against Grima?

The ceiling collapsed on Lucina and once more did Grima let out a vicious roar. With the last of her strength, Lucina reached for the foot of the Shrine of Naga. A bright green light illuminated the room and then the whole castle was destroyed.
