World Tree

«Yggdrasil» is the tree that is at the center of ALfheim Online. The name "Yggdrasil" in Norse mythology means "World Tree." It was said that the tribe which reached the legendary city floating above Yggdrasil and had an audience with Fairy King Oberon who lived there would be reborn into true fairies, the ALF.

The hover limit imposed on the system would be eliminated and unlimited flight would become possible. Along with it the successful tribe would be capable of becoming rulers of this infinite sky. It was said to be possible to enter this floating city through a dome at the root of Yggdrasil.



However, Kirito discovers that there is no city above the World Tree. Also, Yui claimed that the number of guardians that defended the World Tree was too high and that the Grand Quest was in fact never intended to be possible to completed. This is further backed when Kirito finds that the gate at the top of the tree couldn't be opened by players as it was locked by administrator codes rather than a quest flag.

ALfheim Online


attempts to climb the World Tree on two occasions to rescue the captive Asuna from Fairy King Oberon. The first, a failed solo attempt and the second with Lyfa, Recon, and the Sylph and Cait Sith raid squadrons. However once Kirito reached the gate he found it locked by administrative codes, Yui determined that the gate was never intended to be opened by players. However, Kirito is able to open it by having Yui use the coding from the admin card Asuna dropped from her cage.
