Careful, boy. Lest you value your life so little.

–Gerathon, The Evertree, page 123

Gerathon is a king cobra 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 made using her talisman, The Jade Serpent.

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, though she values her own life and seems to want to avoid death, possibly due to the ordeals she went through while imprisoned.

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 which he did for Meilin and Shane in The Evertree.

Gerathon appears at Muttering Rock along with Kovo and Halawir. When Shane asked for the Staff of Cycles, she agrees with Kovo not to give it to him. When Shane calls her a coward, she threatens to kill him. In chapter 19, she is forced by Suka the Polar Bear into The Evertree to sacrifice herself.

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.


  • Like all snakes, Gerathon only has one lung.
  • Gerathon is the only Great Beast that is a reptile. She and Mulop are the only Great Beasts who aren't warm-blooded animals.
  • There is a mistake in the French version of Spirit Animals (Animal Tattoo). In this version, Gerathon is a male.
  • On the Conqueror letter, the closing statement states "Gerathon demands it,".
