8th Floor (Aincrad)

The 8th Floor (第8層) of Aincrad is a forest-themed floor.

Geography
Although the 3rd Floor also has woods as its motif, the 8th Floor is much more abundant in its forests and only has a few grasslands and rocky surfaces, while the entire surface of the floor is covered in fathomless water, rendering the surface unwalkable. Players have to use suspended paths, the branches of the humongous (though far smaller than the World Tree) trees which spread in all directions or man-made suspension bridges to get around the floor.

In Sword Art Online, falling down meant searching for a tree with a ladder and going right and left through the water, but this problem is not present in ALfheim Online, as all players have the ability to fly back to the top. The trees on this floor are so large that they even touch the underside of the 9th Floor, making it near impossible to ascend over the forest, however, the 8th Floor is one of the few floors where the players can touch the underside of the next floor, if they are good at tree climbing, though it’s still impossible to dig a hole to the next floor.

In Sword Art Online, the trees on this floor were all verdant green, however, in ALfheim Online, due to changing the plot to adjust for the new Labyrinth Boss, the trees surrounding the Labyrinth were all changed to charcoal-black burnt trees.

Friben
«Friben» Village is the main settlement of the 8th Floor.

Labyrinth
The Labyrinth of the floor is a huge tree (this tree is charcoal-black in ALO due to a change in setting).

History
In New ALfheim Online, the Clearers reached the floor at around June 14, 2025, however, as the bosses of New Aincrad were much more difficult than their counterparts in the original Aincrad, the boss of the Labyrinth had forced full raid parties to flee multiple times over the period of about week. Only after multiple defeats, each time getting closer and closer to depleting the boss’s HP, the Clearers managed to witness how the boss acts when it is down to its final HP bar and on June 23, 2025, another full raid, including the forces of General Eugene and Lady Sakuya was gathered and, likely, managed to finally defeat the boss and clear the floor.

Known Bosses
