and some info

they are from my fictional universe called limozena, and wielding is what they call abilities. full blooded humans who live there are the only species that cannot possess wielding unless given. so humans can't be born with wielding properties. ink wielding is basically being able to summon black liquid which or isn't made of pure ink. the wielder can basically transport into the void and teleport to other places that way. and blood wielding is where you can control people via their blood inside their body, or make blood into weapons. healing is self explanatory. onto the backstories

William's backstory, which contains descriptions of murder. William wasn't always a Demon type of creature nor immortal. In the year 14140 in Limozena, William lived as a normal full blooded human. Instead of going home after school, William decided to go to a forest with his friends. They found a spot to chat and be themselves, one of the people decided to leave the others. The person came back in a hurry, telling them of something demonic he encountered. They all laughed it off like the person was playing a joke on them. But the person was being serious. Night fell, they decided to start heading back home. But the person from before heard a noise, and something happened. All of William's friends were killed in front of him as a demonic creature stood over him, he was the only one left. The creature did no harm to William, the creature melted into some black liquid. Before William could react, the black liquid got onto him and started to inject itself into William through his veins.

William would let out a pained groaned as the creature was successful. William's body fought the creature/liquid like it was some disease. The creature was trying to take control of William's body. During this, right sider of William's face was covered with dark liquid, making him blind in his right eye. His arms started to become black as well with the liquid. But the creature stopped, it was satisfied with where it is. William changed, everything changed. His eye that was uncovered turned into a red, for it was originally brown. His canine teeth became sharper, and he could digest flesh of other humans, like Ericas. For years he had been killing and devouring humans and even some hymauis. But murdering one girl got him in prison that was inescapable to him. Sometimes the demon side of him would take control and sometimes he would take control. The demon can only be heard by him, and they are now bit of a team.

Derek's backstory, contains descriptions of experimenting on living beings and murder. Derek was a scientist in the Redlands but eventually moved to South Limo in Earthaina to continue his work. When he was fired from work, he was pissed off, and that sparked something in him. Derek kidnapped his boss's children and family, and experimented on them. Soon he would send them back to the boss anonymously, some alive and some not. Those who were alive were deformed and ripped apart. Derek found joy in doing this, so he continued. Eventually, he was caught and happily complied with his sentence. He is William's roommate, and they are working together to break out and ensure chaos onto the world.

William's home wasn't the best. It was strict, sexist, and sometimes verbal abuse occurs. Derek's workplaces weren't the best either, he was always abused as an employee. All of the experiences led to them becoming villains. William had no problem with working with the demon that infested him. And Derek had no problem with harming those who wronged him by experimenting on their families and children, and sending back their corpses or half-dead children/family members. They are truly messed up.
