History
The World of D-Gray Man seems to be based on the old testament of the Bible. Nothing is known about what happened over 7000 years prior to the story. 7000 years ago the World was flooded after the fight of the Heart wielder and the Earl of Millennium. The 12 remaining noah sheltered in the ark and became the ancestor of Humanity. Their descendants, the current humans seem to have populated the earth. The last millennia seem similar to the historical reports of the real world.

When the Cube was discovered about 100 years prior to the story, an organization named the new world alliance founded the Black Order which started gathering innocence shards and accomodators to fight the Earl of Millennium. The storyline takes place at the end of the XIXth century.

Factions
The holy war is obviously opposing belligerent parties:
 * The Black Order: 100 years old, this organization has as primary fighters the Exorcists. They wield the innocence (see below) and fight the Noah Family and their forces.
 * The Noah Family: Led by the Millennium Earl, this at least 7000 years old faction supports the end of Humanity and the achievement of the 3 days of darkness. It uses an army of Akumas.
 * Apocryphos: Stemming from the Innocence side, Apocryphos doesn't seem to share the exact same goal as the Black Order. He only breaths to protect the Heart of Innocence.
 * The 14th: Stemming from the Noah side, the 14th declared his will of replacing the Earl of Millennium. He seems to have supporters.

Skills and Materials
The World of D-Gray Man is only inspired by the real world. It has its own specificitied. These include:


 * Dark Matter: The weapon of the millennium Earm and his allies, dark matter is a very dangerous power that allows its users to do various actions.
