Hmmmm....while red dragons come in close, they are almost edged out slightly be shadow dragons. The shadow dragon has served as a principle villain in more than a few of my campaigns (though so has the red!) so I guess I'll make it a tie.
|Most notable red dragon of my games was Rovas, the guardian of the vessel of Tiamat, a colossal ancient red.|
|Most notable shadow dragon appeared recently as the guardian of the Pillar of Eternity, the Nightwyrm.|
