Twilit Fossil, Stallord (蘇生古代竜 ハーラ・ジガント Sosei Kodai Ryū Hāra-Jiganto, Resurrected Ancient Dragon Hahra Gigant) is the boss of the Arbiter's Grounds, the fourth dungeon in The Legend of Zelda: Twilight Princess. Stallord is the skeleton of a dead beast found inside the Arbiter's Grounds. It has a roughly humanoid upper body protruding from a pit of sand, and a horned animal head comparable to a goat or dragon. Its lower body is never seen; in fact, whether its lower portions were even present at the time is unknown. Several weapons are embedded in the beast's skull, possibly the cause of its death. The music played during the battle against Stallord incorporates, partly, reinstrumentalized versions of the music played during the battles against King Dodongo and Volvagia in The Legend of Zelda: Ocarina of Time. By name, it is the king of the Stalfos in Arbiter's Grounds.
