When the First World fell it is said that the Mother of Dragon’s, Tiamat’s, rage at her loss was so great that nothing, not death, not imprisonment, not the aeons since could quell it. Her fury echoes still across the Material Plane, joined in chorus by her Chromatic children, resounding in the very bones of the earth itself.
It is this most ancient of angers that the Path of the Wyrm Barbarian channels within them. It beats within their hearts, tying them to the elemental powers of the Material Plane and surges in the souls of those who dragons have changed the lives of.
Path of the Wyrm Barbarians are able to channel the elemental powers of chromatic dragons in their rage, giving them choices for elemental resistances and damage when they rage. At higher levels their bodies and very presence gain some of the notable traits of Dragons in 5th Edition as well as improving their elemental abilities.
