Gravity purchased the worldwide distribution rights for all regions except Japan from GungHo Online Entertainment Inc. in November 2005.
Run Up launched the official Malaysia and Singapore web sites for the game on July 3, 2009.
The main stage is set in the land of Acronia, situated in the Emils' world, with the city of Acropolis at its centre.
There was a great effort to rebuild and regroup as each race reclaimed their rightful spot in the world.
Each SAGA usually opens up a new area in the map and many introduce new systems to the game.
In SAGA 9, Primula, a guide fairy for beginners, and ECO town were introduced.
Primula helps players who are rather new to the game and don't have much experience in people and places to complete quests.
Some items, like motorcycles and mini-maid costumes can be bought here in addition to those already available in the Dominion world for players who can't battle well.
In the main storyline quests and holiday events, the four races are each represented by a pair of NPCs: Emil and Marcia for the Emils, Titus and Tita for the Titania, Belial and R'lyeh for the Dominion, and LILI (formerly known as the Mysterious Girl) and LUX (formerly known as the Mysterious Youth) for the DEM.
There are 13 jobs classes in Emil Chronicle Online, including the Novice which is what all non-DEM players start out with.
Jobs in ECO is separated into 3 main groups (Fighter, Spell User, Back Packer).
Fighters are classes that focus on dealing physical damage and consist of the Swordsman, Fencer, Scout and Archer.
Spell Users, as the name suggests, are the magi of the game and this group is made up of the Wizard, Shaman, Vates and Warlock.
In addition, there are two Joint Jobs, the Breeder and Garderner, that are accessible to all players after completing the relevant quests.
One can possess the upper armor, the chest accessory, left or right hand equipment.
Piggyback monsters, also known in the English and Indonesian versions as "Cattys", are cat-like spirits that are modelled after the nekomata.
In addition to supporting their masters with skills, the Cattys also increase the owner's item capacity when equipped.
Within the game itself is a virtual theater operated by a well-known anime production company of the same name.
The area, which looks like a movie theater, will show promotional clips of exclusive content and staff interviews.
With the Iris Update on May 28, 2009, Emil Chronicle Online Japan removed the monthly fee and enhanced the Cash Shop.
