Cleared floors:
- FLOOR ONE: Town Of Beginnings - The city on the 1st floor of Aincrad. It is capable of housing over six thousand people. It is also where a majority of the non-players in SAO reside. It has a large road paved with stone, and medieval streets surrounded by street-lights.
- Black Iron Castle - not much information is known about this area, it also appears that its not included during Close Beta and was released only during the official launch of the game.
- Black Iron Castle Dungeon - only few players has ventured on this parts, and covered only the first half of the entire sub floor. It is said to be teeming with powerful monsters above level 40.
- Monument of Life - is a large stone tablet that replaced the Room of Resurrection in the official server service of Sword Art Online. It lists all the names of the 10,000 players of SAO. The names of the dead players are automatically crossed out, with the cause, time, day and month of death written beside it.
