Unite them all
The four kings it was a term that Quinn had learnt not too long ago and had heard about it recently as it had popped up again. Still, he didn't know too much about it or about them. When first obtaining his own familiar the Boneclaw, he had heard it be called the Undead king from the others.
Some thought it was just a title due to its appearance and great strength as a familiar. According to Leo, who had travelled to the familiar world with the others, it wasn't just a title. It was a name that had been given to it in the familiar world. Something that the other familiars also knew him as.
A large world with familiars all around that lived off a certain type of energy. Here there were four rulers.
"The Bone Claw, Leo's Cat and Oscar's Horse," Quinn mumbled as he went through them all.
