Chartilifax, the large green dragon is the last boss of the Lair of the Mad Dragon dungeon. "Dragons once ruled the other races as the undisputed masters of the earth and sky. For millennia, they populated the Forgotten Realms, without ever meeting anyone who challenged them equally. Everything has an end, however, this ancient breed has since declined. Dragons of today are a shadow of their former glory, but are still among the most powerful creatures of Faerun. Only a fool or a hero would dare to challenge a dragon without companions."
