The Demon Lord Krebskulm has awakened due to Alicia's betrayal. Diablo stands alone against Klem, her mind consumed by hatred. Shera races to Rem's side. An army of Fallen led by Edelgard marches on Faltra, and the curtain rises on their final battle.
Because I've peered into an abyss that 
the likes of you couldn't imagine.
Ich habe in eine Kluft geschaut,
die ihr euch nicht vorstellen könnt.
Porque vi un abismo inconcebible.
Porque he visto un abismo inconcebible.
C’est parce que je regarde un abîme
que tu ne peux même pas imaginer.
Perché ho scrutato un abisso 
che non puoi neanche immaginare.
Eu olhei no fundo de
um abismo inimaginável.
Взгляд мой блуждает по бездне бытия,
что глубже твоего понимания.
