Diablo resolves to return to Zircon Tower at once after learning the city was under attack by the Demon Lord Army.

Meanwhile the desert becomes a battlefield as Laminitus and her soldiers wage battle against the Demon Lord Army's Commander, Varakness. Laminitus struggles against the overwhelming might of the Fallen, and just as the final blow is about to be dealt to her, Diablo appears with a flash.
I can't turn a blind eye to a Demon Lord
 and a Fallen within the city.
Ich kann nicht zulassen, dass Dämonen und
der König der Dämonen in der Stadt leben.
No puedo ignorar a una señora demonio
y caídos en la ciudad.
No puedo ignorar a una señora demonio
y caídos en la ciudad.
La présence d’un roi démon et d’un démon
dans cette ville ne peut être ignorée.
Non posso far finta di nulla 
con un Re dei Demoni e una Decaduta in città.
Não posso fechar os olhos para Lordes Demônio
e Corrompidos dentro da cidade.
Я не могу закрыть глаза на демонов
и Владыку, раз они бродят по городу!
