Relentless Species Guide


A race of human/demon warriors that protects humans from vampires and other supernatural threats, mainly demons. The Mohiri were created by the archangel Michael after demons began to walk the earth and one demon in particular, the Vamhir demon, threatened the human race. He took a parasitic demon called a Mori and places it inside a human. The Mori made the human immortal and have them the strength and speed to fight other demons, and in return the human gave the Mori a host. Thus, the Mohiri race was created and every Mohiri after was born with a Mori inside.


Young Mohiri are taught to control their Mori, which would take control of their body if it’s not reined in. Despite the symbiotic relationship, Mori are sentient demons with the natural urge to be in command. By the time they reach puberty, a Mohiri lives in harmony with its demon. They are twice as strong as humans when they reach adulthood, but it takes up to a century for them to reach their full strength.


The Mohiri live in fortified strongholds around the world. They believe strongly in family and community, and children are protected and nurtured. They start warrior training when they are thirteen and they become warriors when they are eighteen. Some go on to be scholars, healers, and educators while the rest are dedicated to hunting their main prey and enemy, vampires. Young Mohiri are twice as strong as humans, and they get stronger as they age. They reach their full strength at around one hundred.



The vampire is created when a parasitic demon called a Vamhir infects a human host by attaching itself to the heart and brain stem. The demon takes control of the human, who is conscious of the invasion, but powerless to stop it. Vampires are immortal and live off human blood. They can sire another vampire by sharing their blood with a human, which causes a new Vamhir to grow inside the human. The transformation can take up to 3 or 4 days.


New vampires are twice as strong as a human and they grow stronger as they age. They are fully matured at 100. Over time they will build up tolerance to daylight as well. Older vampires can handle exposure to daylight as long as it’s not direct sunlight. New vampires can’t tolerate daylight for longer than a minute. Vampires can be killed by beheading, fire, a weapon through the heart. Silver burns them. They can be solitary or live in nests of up to twenty. Nests usually have one or two mature vampires and the rest are young.



An old and powerful vampire with powers beyond a normal vampire. They are they only vampire than can compel other vampires, and they surround themselves with a loyal army of vampires. They are almost invincible and only beheading or Fae magic can kill them. They stay in hiding and their identity is their most close-guarded secret. Master are the only vampires that can compel the Mohiri, who are immune to normal vampire compulsion. The only way to become a Master is for a vampire to kill another Master and drain them dry.



Werewolves look like everyone else in their human form. In their fur, they are as big as a bear when they are on four legs. They can stand on their hind legs and use their front legs like arms. They have bristled hair that comes in different shades, short pointed ears, yellow eyes, and a long snout. They are fast and strong and natural vampire hunters. They can only be born, not made. Silver is poisonous to them.


They live in packs with run by an Alpha and his Beta. The Alpha has the ability to command the entire pack with his will, and when he issues a command, it cannot be ignored. Many packs live among humans, but keep their true nature a secret from the humans.


Once a male reaches maturity, his wolf will be able to choose a mate. This is called imprinting. When it happens, the male will release a mating scent that is pleasant only to the female he has imprinted on, and it lets other wolves know he and she are taken. When an imprinted couple has sex, they are mated for life.


Wolves are natural hunters and their hunting instinct kicks in when they reach puberty. They go off hunting at least once a month to contain these instincts.

Undines, like all elementals, have the ability to heal and their power comes from the earth. Demons fear them because Fae power is lethal to them.
