According to the information Blavi had, Archknight Fernando had ordered his entire army to attack Reddenburg after Anfey had left Shield of Light legion with Ozzic and a few others. It would take Anfey a few days to go back and forth, so he figured Fernando would have taken Reddenburg during that time. Anfey asked Ozzic to take his unit to the front and travel directly to Reddenburg.
It was not a peaceful trip. Many death spirits came at them like one swarm of flies after another. Fortunately, these death spirits could not pose any threat to a group of more than a thousand mercenaries and were killed. After fighting this kind of battle against zombies, mercenaries seemed to get used to his kind of weak attack.
