Nerita said that all the necessary information about the Balaur had been obtained and asked you to oust the Bakarma Legion from Beluslan. He said that it was only because of the Aetheric Field Suppressing Device that the Balaur were able to live in Aether-rich Atreia, and that destroying the suppressing device would cause them to leave. You met Governor Votan at the Primum Landing in Reshanta so you could get the Powerful Aether Bombs to destroy the Balaur Aether-consuming Stones protecting the Aetheric Field Suppressing Device. Afterwards you took the Powerful Aether Bombs to Nerita, who tasked you to infiltrate the Draupnir Cave and get more precise information from the spy Fafner. When you found Fafner, who had disguised himself as a Drakie, he told you where you could find the Aether-consuming stones and the Aetheric Field Suppressing Device. You destroyed the four Guardian Stones one by one using the Powerful Aether Bombs from the Abyss, and then eliminated Brigade General Yavant who was linked to the Aetheric Field Suppressing Device. When you reported to Nerita that you had been successful in the Beluslan Fortress, he praised you and sent you to Pandaemonium to inform Governor Vidar. Governor Vidar was delighted that the Aetheric Field Suppressing Device had been destroyed and promised to make your achievements public.
