Reference Text

Ancient red dragons are the most powerful and feared of the chromatic dragons. They are immense, with scales like molten rock and wings that blot out the sun. Their lairs are typically in volcanic mountains or deep caverns, where they hoard vast treasures and rule over lesser creatures with terror. They are creatures of pure destruction, delighting in burning entire kingdoms to ash. Their ancient age grants them immense magical power and cunning, making them nearly unstoppable foes.
