The continent of dragons, occupying the southeastern part of the world. Far east of Khorvaire and south of Sarlona, Argonnessen is almost totally unexplored by any race of Khorvaire due to the fact that it is inhabited primarily by Dragons. The continent went to war with Aerenal and destroyed the Giant civilization. Off of Argonnessen lies the island of Seren, inhabited by largely savage, dragon-worshipping barbarian humans. Argonnessen (and Seren) are, for the most part, off limits to the “lesser races” (which includes almost everyone except a dragon). Many of the continent’s dragons are members of a group known as the Chamber, which interprets the Draconic Prophecy and uses it to shape the world to the dragons’ liking.
Unlike most dragons in Dungeons & Dragons, there is no correspondence between a Eberron dragon’s breed and its alignment. Thus, a silver dragon could be evil while a red dragon could be lawful good.
