Midgard

At the end of Fairy Dance Arc, with the sprouting of the «World Seed», some of the old ALO players funded a new company, Ymir, which bought all of the ALfheim Online data from RECT Progress Inc. for a small fee and discovered that a complete copy of the castle existed on the server. As the company had to fight a decrease in the playerbase due to RECT Progress' inhuman experiments and because the company was formed by veteran MMO game players who had been playing since the 2D age and could not bear the deletion of the intricately designed castle, the castle of New Aincrad was implemented into the ALO world, floating above the continent of Alfheim, on May 2025.

The castle is currently being cleared by guilds and players without a guild. Such raids are led by high-level players like General Eugene.

Changes

The castle is essentially identical to the original Aincrad, except for a few key features. First, the bosses and dungeon monsters were made significantly more difficult, as there is no threat of real death in the ALO's Aincrad. Dungeon maps and similar features were likely re-done, as the Clearers in ALO continue to utilize mapping and scouting strategies on bosses, while all the bosses were changed to brand new ones. The last known change is on the Monument of Life. After this update, the monument, which before used to list existing players who were still alive at the time, is now called as the «Monument of Swordsmen» and is used to list players who participate in clearing the boss of each floor. As the monument can only record seven player names for each floor cleared at most (due to space limitations), if more than one party participates in the battle against the boss of the floor, only the name of the leader of each party will be listed on the monument, however, if one party of up to seven players is able to beat the boss on their own, the name of each member of the party will appear on the monument.[29]

Features and Restrictions

Since Aincrad was fused with ALfheim Online's gameplay, the system was also designed to re-account for magic, flying, and the new limitations and additions with Sword Skills. It is now possible to fly from floor to floor in ALO's Aincrad, although the outer circumference is closed for floors which have not yet been unlocked.[17] Additionally, a flight altitude limit for players is set at the level of the 50th Floor, preventing players from examining the outside of the floors above it, including the top of the castle.[17][48] Dungeons are no-flying zones, and the Remain Light system was incorporated from ALO.
