“Okay, I don't mean to freak anyone out, but I'm pretty sure that's a kraken.”
The Kraken is a huge green aquatic beast that was mentioned in Everblaze. They look like a mix between an octopus, an elephant and a lion. These creatures have six fangs, trunklike, tentacled noses and slimy bodies. Sophie, Keefe and Sandor encountered a kraken when light leaping, using the light from the unmapped stars to test the Black Swan's security. Later in Neverseen, they are referenced and it is revealed that they live in colder water, as the Black Swan's eastern hold was too warm for them to have been. In Flashback, Keefe gives Sophie a kraken Prattles pin named Krakie while she is recovering in the Healing Center.
