Dragonborn

The dragonborn are a fictional race in the Dungeons & Dragons fantasy tabletop role-playing game.

Publication history
The dragonborn was originally introduced in the Dungeons & Dragons 3.5 supplement book Races of the Dragon, published by Wizards of the Coast in 2006. In that book, dragonborn are presented as a transitive race, members of other humanoid races who, to show devotion to Bahamut, willingly took on draconic traits in place of their original biology.

The dragonborn race is a true draconic race in Dungeons & Dragons 4th Edition. They are descendants of the greater Dragon God, Io.

The dragonborn appears in the fourth edition Monster Manual (2008), including the dragonborn soldier, the dragonborn gladiator, the dragonborn raider, and the dragonborn champion.

The dragonborn is detailed in Dragon #365 in the "Ecology of the Dragonborn", and in the book Player's Handbook Races: Dragonborn.

Forgotten Realms
In the Forgotten Realms campaign setting, the Dragonborn came from Abeir (the lost sibling world of Toril). In Faerûn, the dragonborn mainly inhabit the militarized kingdom of Tymanther, but many live in Returned Abeir, the continent that has replaced Maztica as a result of the Spellplague. The Dragonborn of Forgotten Realms have a deep hatred of true dragons, for in their previous world of Abeir they fought terrible wars against them.

Eberron
In the Eberron campaign setting, the Dragonborn are descendants of the dragons of the lost continent of Argonessen, where they have lived in isolation since before Khorvaire's founding.

Dark Sun
In the Dark Sun campaign setting, the Dragonborn are created from humans by the sorcerer-king Dregoth, and refer to themselves as Dray.
