Hunter's Notes
A legendary black dragon said to have prowled these lands from the days of old. Many skilled hunters have sought to challenge it, but none ever return. A monster shrouded in mystery...
The Hunter's Encyclopedia gives the classification of Fatalis as unknown. Its pitch-black body earned it the name black dragon, and it may keep the old form of the first dragons better than any other kind. Famous hunters are said to have fought it, but no one can confirm those stories.
