A misty fishing village was being overrun by zombies. While there, she is reunited with Quolkeh, whom she first met at the Adventurer's Guild in Helshper. Quolkeh tells her that they and their comrades hadn't been able to leave this fishing village surrounded in fog. Quolkeh then leads Cayna to their base that's underneath a storehouse. Cayna then sees Exis who was protecting the one and only girl from the village who had survived...

Así que la causa de la niebla
será un monstruo o algo similar.

Então a causa da névoa deve
ser um monstro ou algo assim.
Ну если так…
