Yaboku

Yaboku (Ya-boo-ku), is Abiel's familiar that usually takes on the form of a cat. Being a familiar he is a magical creature that does not require to breathe, eat nor sleep, making him an excellent watcher and scout. Thanks to wearing the Collar of Familiar Protection he has access to one cantrip of Abiel's choice, which is Eldritch Blast, making Yaboku contribute to his masters general damage output by a lot.

Description
Most of the time Yaboku appears as a black cat that has blue eyes and that wears a light blue / cyan collar around his neck. But he has also appeared as a black moth before, and other small animals. Though usually no matter the form he is black in coloration and wears some semblance of his collar.

Personality
Quick to listen to his master, Yaboku is obedient and loyal to Abiel and anyone Abiel asks him to be nice towards. He rarely ever questions the command of Abiel and happily sacrifices himself for the sake of the party's safety. When spoken to as a individual he is just a bit skittish, seeming to not enjoy expressing his personal thoughts much. If Abiel falls unconscious on the battlefield or is damaged badly by something, he ensures that revenge is brought.

Background
Abiel likes cats, thus Yaboku is a cat. Like most familiars he originally comes from the astral plane, a spirit drawn from the massive sea of souls to be given a physical magical form and a new purpose. What he used to be before becoming a spirit and a familiar is unclear.

Powers
Yaboku is capable of the following things based on observation:
 * Using Eldritch Blast, through the collar
 * Being summoned and dismissed whenever
 * Being basically immortal unless Abiel dies
 * Doing cat things
 * Acting as a communication device
 * Telepathy
 * Taking on different forms
