How I Stopped Worrying and Learned to Love Eberron
These draconic humanoids may strike an imposing figure, but they are no more dangerous or powerful than the average human. There are many theories about the connection between the dragonborn and dragons, but little evidence. Rumors of an ancient dragon in the east of Q’barra and his dragonborn retinue is cited, but no documentation exists to back it up.
Some explorers report seeing dragonborn in Argonnessen, but no Khorvairian dragonborn was born there. The largest known dragonborn community is in northern Q’Barra, based around Kar’hashan. Their myths tell a tale of exile and travelling into the deep jungle, fighting off the local lizardfolk (it is a point of contention when a dragonborn is mistaken for a lizardfolk). They have a strong martial tradition, and the occasional dragonborn mercenary would appear during the Last War.
