The world of Venas. At first glance it seems to be a paradise. Resources were plentiful and renewable, rarely did any wars between human nations ignite and the faithful were protected by the gods and their servants. However every paradise has a dark side. Venas' darkness comes in the form of a crimson liquid. Blood.
Here in Venas blood is power, even more valueable than gold or silver. Blood is magic. Any new comer to the plane of Venas would at first believe that magical power would derive from the soul or another dimension, however they would be awestrucked when they realize that blood is the one true source.
All magic comes from it, even the gods themselves would have their followers commit ritualistic sacrifices in order to collect more and more of it. Human mages would often collect their blood from excuted prisoners at cities or even midway in a battle from the dead corpses of fallen enemies. The more blood you had the more power you had. However it wasn't easy to use it.
Collected Blood was not stored in containers or jars as one would believe, instead a mage's Blood would instead be stored in a specialized material or gem called a Viscer Gem which is a often artificially grafted into the mages body and over a short period of magical processes the Viscer gem would be fully intergrated into the host'a body and become a vital organ. Viscer gems are usually made out of a crystalline material such as quartz or a ruby, with the most sought after being diamonds or obsidian. Viscer gems often were a mages most vital item, a Viscer Gem stores all of their magical energy and is often their main source of power, but a Viscer Gem is also their weak point. A damaged Viscer Gem is the same as a damaged heart or brain. If a mages Viscer Gem is destroyed, the mage will die along with it. Because of this, a mage will often have the gem hidden or attached somewhere that can be hidden easily such as a leg or arm, mages are also known to plant decoy gems around their bodies or clothing in order to dissaude any would be killers.
Overusage was also a dangerous part of Blood magic. Overusage could lead to death or even an unearthly addiction to blood often leading into a vampire like transformation, where even the sun would dam you for your crimes. Blood magic was also picky on who could use it or who could not. Only those who come from special bloodlines could harness the power of Blood. These bloodlines often come from cross species breeding with humans and a mystical creature such as a dragon or kitsune. Magical Bloodlines could also start suddenly within normal families and even families with the most prestigious arcane bloodline could see their arcane power fade with each generation. Some who faithfully service their god could also be blessed with a magical bloodline. There are even rumors that each bloodline also has its own unique qualities and powers as well. Though only the noble magicians knew whether these rumors are true or not.
However there was one way of gaining a magical bloodline that everyone knew and feared. A way that would surely gain the hatred and fear of even the kindest of people, and a way that would cause you to become a target of all angels and holy Blood Clerics. It was to become a Demonblood.
Demonbloods were known as the most powerful of mortal bloodlines, with potential being able to match that of ArchAngels and possibly even Gods themselves. They were always monsterous in appearance, often taking a large resemblance of their creator. They were created by the anti-gods, the seekers of chaos and the destruction of the Gods. The Demon Lords.
When a Demon Lord wishes to create a Demonblood they require to go the mortal world. A Demon Lord or also sometimes called an Omega would travel to the realm of humans and seek out a pregnant mortal woman who would soon give birth, these women were often in poverty or bad times, desperate and lost. The Demon Lord would personally create a pact with the woman, giving them whatever they desired. Then the Demon Lord would then lay a single finger on the woman'a head and proceed to destroy the soon to be born soul of the pregnant woman's child. Then the Demon Lord would replace the child's soul with a shard of the Omega's own soul, thereby making the Omega and the newly created Demonblood linked together and creating a demonic bloodline with the Demonblood also becoming a part of the Omega itself . The child would later be born as a Demonblood, forced to be raised by their parents as the Omega's latest creation and weapon.
You knew all of this, from a young age your parents told you this and that at the age of sixteen you would be sent to your demonic soul sharer. You were a Demonblood. Dammed by everyone, and your demonic patron was...
