Tranquil Seas Vol.2: A sequel to 'Tranquil Seas'

The continuation of the story of Y/n Lugia, this story takes off directly after the finale of the first book.
Following the battle between Lugia and Yveltal, Beacon was left in shambles. Mass evacuation of the students, destruction of the tower and most other buildings, and the defeat of Y/n, there's little left but rubble in a courtyard.
That's when Y/n wakes up from a long coma, five months later. With his niece traveling the world with the former teams RWBY and JNPR, and his children and friends gone to find their own way to defeat Yveltal, he now must question whether or not he can truly trust his memories and past. Who is this 'student' Y/n keeps having flashbacks to? And what is the secret past between Y/n and Yveltal?
