A. Up until this point everything you've experienced has been backlash from the last two boards. It was just to get you familiarized with the system and the idea of the euphoric and battle.
B. The tournament was a distraction and a brief interlude that was only meant to put everyone in the Winmei when Nema was awakened.
C. Yes, there will be another, REAL tournament.
D. Cannibalize ability is active in any tournament but since this one was fake and just meant to be a trap you haven't received or lost anything.
E. The Hymn is an automatic upgrade to all your euphoric now that you are all technically caught up with what occurred in the last board. Because the last board ended with the Phantasmal as well.
F. Welcome to the REAL board. The game now begins. You're all introduced to the battle system, know your Euphoric, (Felimay will be replaced by Regal once she is registered so those of you assigned to her have lost nothing.), and know a good outline of the general history. If not, ask and you shall receive.
