Taking Over the Wall
Beast was the one to move the monster portal to the wall. With his flying beasts, he was able to get back to the portal very quickly while the rest stayed back at the wall. He had brought Blackie with him just in case something was to happen, but nothing of the sort happened in the end.
The army was exhausted, they had fought with everything they had, as did Wolf and the others. The healers were barely conscious as they had used everything they had to heal those that were heavily injured. During the battle, they had focused on only healing such players as healing everybody, no matter the injury, was simply far too taxing, which would lead to them losing their mana quickly.
Heavy injuries, missing limbs, and near-death conditions were the only ones they had healed, and yet, even then, they weren't able to heal everybody as their mana was dwindling rapidly, even with them using mana potions to recharge themselves.
