After completion (spoilers)
"It's high time we leave this island." After completing your Ascension, you returned to the Forward Base. Nania was making preparations to depart from Poeta, but concern soon arose when the legionnaires stationed outside the base suddenly fell silent. You traveled to the sky island in search of the missing legionnaires, only to find them dead or gravely wounded. As you tended to one of the survivors, the Balaur launched an attack. After driving back the enemy, you returned safely to the Forward Base.
