SPOILER WARNING: Plot and/or ending details follow.

Gerathon is a serpent Great Beast. She is one of the two Great Beasts that controlled the The Devourer in the first war, the other being Kovo the Ape. She also created the Bile, which is her venom.

In the second series, she is summoned as a spirit animal by a girl named Raisha.


Gerathon is a huge cobra with black scales[1], a yellow underbelly[2] and black eyes with a gold rim.[3] She was also mentioned to weigh over 2 tons. She is considered very dangerous and apparently cares little for human lives.

She can send her conscience to anyone who has drank the Bile and control them; however the control can also be broken if the person's willpower is strong enough (ex. Meilin and Aidana). Tellun also has the power to cure any person from the Bile without breaking their bond with their spirit animal.

Gerathon's talisman is the Jade Serpent. It creates and controls the Bile.

Tales of the Fallen Beasts

Gerathon was summoned by Raisha, a loyal servant of Zerif. Raisha summoned Gerathon in a prison in Zhong, and then a greencloak named Dorell (who also serves Zerif) helped her escape. However Dorell turned on them, and Gerathon killed him and his spirit animal. Raisha blacks out and then wakes up to Zerif's voice. Zerif told her that he knew that she'd summon a great beast. Even after Raisha's loyal actions, Zerif took Gerathon as another stolen great beast.



Despite Gerathon's earlier disdain for humans, she appears to be close to Raisha. They respect each other, and Raisha is not afraid of her spirit animal, and even seems to like her. When Gerathon killed Dorell, Dorell asks why, and Raisha responds that she trusts the cobra. Gerathon attempts to free herself to help Raisha when she is cornered by Zerif.


  • Gerathon only has one lung.
  • Gerathon is the only reptile Great Beast. She and Mulop are the only Great Beasts who aren't warm-blooded.
