The Elf War (エルフ戦争, Erufu Sensou?) is the first campaign quest in Sword Art Online, spanning numerous chapters that take place from the 3rd Floor of Aincrad to the 9th Floor of Aincrad. At the beginning of the quest, the players must choose to either support the forest elves or the dark elves, thus branching the campaign into two main paths with different quests. The campaign quest plays a prominent role in the Progressive Arc.

Campaign ChaptersEdit

Initial QuestEdit

Chapter Name Description
1 Jade Key (翡翠(ひすい)秘鍵(ひけん), Hisui no Hiken?) The players encounter a forest elf battling against a dark elf in the Forest of Wavering Mists. The player must choose one of the elves to support and either kill the other elf or wait for their elf to use a last resort attack to kill themselves and the other elf once the players' hit points reach the yellow zone. The players must then return the Jade Key the elves were carrying to either the forest elf base or dark elf base respectively.

Dark Elf PathEdit

Chapter Name Description
3rd Floor
2 Vanquishing the Spiders (毒蜘蛛(ど くぐも)討伐, Dokugumo Doubatsu?) The dark elf commander requests the players to find the nest of poisonous spiders that were sabotaging patrol missions. The first part of the quest requires the player to find the corpse of a dark elf scout on the first floor of the nest and bringing a leaf-design emblem from the scout to the dark elf commander. The second part of the quest involves killing Nephila Regina, the queen spider of the nest, and then bringing the Queen Spider's Poison Fang to the dark elf commander.
3 The Flower Offering (手向けの花?) A collection quest to gather flowers to offer to the memory of the slain scout from the second quest.
4 Emergency Orders (緊急(きんきゅう)指令, Kinkyū Shirei?) Another search for a missing scout that results in finding the scout alive.
5 The Missing Soldier (消えた兵士, Kieta Heishi?) The scout is revealed to be a forest elf using a disguise charm who attempts to steal the Jade Key. The players form a temporary party with Dark Elven Wolfhandlers to follow the imposter scout’s tracks to a large forest elf camp.
6 Infiltration (潜入(せんにゅう), Sen'nyū?) A quest that involves stealing a scroll of orders from the forest elf camp and delivering it to the dark elf commander.
7 Butterfly Collection (蝶採集, Chou Saishū?) A brief quest that involves finding and defeating a giant butterfly released by the forest elves for reconnaissance.
8 The Western Spirit Tree (西の霊樹, Nishi no Reiju?) A quest to transport the Jade Key to the Western Spirit Tree. The transport is ambushed along the way by Unknown Marauders who steal the key.
9 Pursuit (追跡, Tsuiseki?) A quest to chase the thief through the forest by tracking the Shining Signal, a glowing liquid that one of the dark elves hit the thief with, leaving a trail of the thief's path.
10 Retrieving the Key (秘鍵奪還, Hiken Dakkan?) A quest that involves exploring a large dungeon to find the thief hideout at the bottom the dungeon and defeating the Fallen Elf Commander, then transporting the key to the Western Spirit Tree.
