Dynamis, introduced in February 2004, is a collection of special battlefields designed for alliances with a maximum of 64 players.

As mentioned in the recently released Topics article regarding the Fellowship system, the simultaneous display of characters on screen is limited due to memory restrictions on the client side, which created fears that such expansive battles would create too great of a processing burden. However, the FINAL FANTASY XI Development Team made player enjoyment the main priority, and worked hard to make Dynamis a reality. As of now, countless players have ventured to Dynamis, but the extraordinary difficulty of the areas makes return trips a necessity.

In the last version update, we introduced the new area "Limbus" for an alliance of 18 players to enjoy as often as they wish. The area was created with comments in mind that Dynamis requires too much time and too many people, and as a result, Limbus was made comparatively less demanding. However, Limbus is rather straightforward, and players who have already conquered Dynamis may find the area lacking in excitement. Therefore, we have decided to release new Dynamis areas for advanced players.
