Butterfly Valley (蝶の谷, Chou no Tani?) is a neutral area located in the west side of Alne Plateu in Alfheim in ALfheim Online.


Butterfly Valley is one of the three main passages that allow passage between the race territories and the Alne Plateau,[1] the others being the Rainbow Valley to the east and the Dragons Valley to the south.[2] Butterfly Valley is bordered by the Cait Sith zone to the west.[2]

The valley itself mostly consists of an expansive forest with a river flowing through it that diverges into smaller rivers. Some regions in the valley are higher than others, thus the valley has areas with cliffs and waterfalls that produce rainbows due to light diffraction. The Alne Plateau mountain range can be seen in the distance.[3]

Like most areas in Alne Plateau, Butterfly Valley is not inhabited by any monsters.[1]


Fairy Dance ArcEdit

As Butterfly Valley is a neutral area close to both the Cait Sith and Sylph areas and is not inhabited by any monsters, a location within the valley was chosen for the Sylph-Cait Sith alliance negotiation conference at 01:00 on January 21, 2025. However, the conference was interrupted by a Salamander army, which intended to kill the delegates of both races. However, the attack was stopped by Kirito, who bluffed in order to get the Salamanders to leave but had to duel with the Salamander general, Eugene, to prove that he was telling the truth. After Kirito won the duel and Kagemune helped persuade Eugene to leave, the Salamander army retreated. Kirito and Leafa then explained the situation to the Sylph and Cait Sith leaders, Sakuya and Alicia Rue, and told them that they would like to join them in their attempt to complete the Grand Quest. Kirito gave 100,000 mithril Yrd pieces to support the raid party financially, before the Sylphs and Cait Sith took their leave. After a short conversation, Kirito and Leafa also took off and headed towards Alne.
