The Everlasting Dragon is an enormous Stone Dragon in Dark Souls that can be found nesting at the far end of Ash Lake. It is one of the last remaining dragons in the world, descended from the ancient Stone Dragons that were defeated by Gwyn and his allies at the dawn of the Age of Fire. Praying before it will allow the player to join the Path of the Dragon Covenant; members of this Covenant can compete in a special PvP mode to earn Dragon Scales that can be offered to the Everlasting Dragon in exchange for unique items and abilities.
The Everlasting Dragon is immortal and cannot be damaged or killed. Players can cut off its tail to receive the Dragon Greatsword weapon; however, doing so will not cause the Dragon to become hostile to the player, nor will it break the player's allegiance to the Path of the Dragon Covenant, should they already be a member.
