The underworld forces hit Palgrost's Southern defensive front one day after its Northern front. Leviathan's vast body loomed over the marching demon hordes. The sight of this colossal devil was unmissable. Even when the defenders were fighting the demon's vanguard troops, their attention was quickly drawn to the huge devil coursing through the sky.
However, before Leviathan came near the defensive walls, he was blocked by another being not smaller in size. This being was a colossal whale with a pair of feathered wings. The wings were too small for its huge body, though. They were more likely just decorations. What truly carried the whale in the sky was the large amount of water floating around the whale. The whale was cruising off this water as it moved.
This whale was Harmony Keepers' guardian, the Caelum Whale. It was level 96 eternal grade.
