Floating Castle Aincrad, Floor Data: Third Floor

The design theme of this floor is "forest". Unlike the woods near Horunka on the first floor or the southern area of the second floor, the third floor is covered entirely by enormous ancient trees. The southern area of this floor is called the Forest of Wavering Mists, a baffling place choked with thick fog. The main city of the third floor, Zumfut, is built inside gigantic hollowed-out trees. There is a dark elf stronghold at the south end of the forest and a forest elf stronghold at the north end. These act as the bases for each side of the campaign quest. The bases have tents for sleeping, eating and even bathing, so players in the midst of the quest have no need to return to town. A field boss guards the tiny pass between the mountains, beyond which is the northern area of the floor and the labyrinth tower.

The boss of the third floor is Nerius the Evil Treant. Nerius takes the form of a giant walking tree, and like Illfang the Kobold Lord and King Asterios, its attack patterns have been changed from the beta test.
