In ALO spricht sich die Entdeckung des Schwertes “Excaliber” herum. Das kann sich Kirito natürlich nicht von jemand anderem wegschnappen lassen! Also macht er sich mit seinen Freunden auf den Weg, das Schwert zu holen. Doch hinter der Quest steckt mehr, als es zunächst den Anschein hat …
One day at the end of the year, Kirigaya Suguha showed her cousin, Kirigaya Kazuto, a news article about the legendary item, the «Holy Sword Excaliber», being discovered in ALfheim Online. Without delay, he called Asuna, Klein, Lisbeth, Silica and Sinon to challenge the dungeon in the sky of Jötunheimr, where Excaliber was . After preparing their items at Lisbeth's arms shop and purchasing potions for the adventure, the group entered Jötunheimr via a secret passageway in Alne. At the end of the tunnel, they reached the top of Jötunheimr and Leafa called Tonkii, a flying evil-god-class monster that they had befriended several months ago. The group climbed on Tonkii's back and asked it to ferry them to the ice dungeon. However, along the way, Tonkii suddenly dived and stopped at an altitude where they could see the ground. There they saw that players were cooperating with the humanoid evil-god-class monsters to massacre Tonkii's kin, the beast evil-god-class monsters. As they were watching the scene, a giant NPC, the «Queen of the Lake» Urðr, appeared behind them. The NPC explained that the massacre was ordered by the king of the giants, Þrym, who once threw the Holy Sword Excaliber into Urðr's Spring and caused the world of Jötunheimr to turn into an icy wasteland. She then explained that if all of Tonkii's kin were slaughtered, she would lose her power and this would allow Þrym to invade the land of the fairies, Alfheim. To prevent this, Urðr requested the fairies to retrieve the Holy Sword Excaliber from the bottom of the ice dungeon, called Þrymheimr.

從MMO明日報得知ALO中的希有武器"斷鋼聖劍"取得方式已被發現的和人及直葉,回想起先前因為直葉的要求出手救援,外型為水母和大象綜合體的邪神"當嘰"，且當時無意間發現斷鋼聖劍就在世界樹的正下方，不過因為距離及取得方式不明，當時並沒有辦法取得。和人看到消息後決定集合大家一起進行斷鋼聖劍任務。當他們再次遇見當嘰後，才發現MMO明日報上的任務,和他們實際接到的任務之間，隱藏了相當巨大的陰謀......
