Gods exist. Their are all sorts of gods out there and how they exist and why they exist is kinda complicated but if something needs a god then one will manifest. You've been interested in gods afterall your family is kinda obsessed with them so naturally you hear about them quite alot. You're family does not love you. You don't really know when it started but they just seems to hate you and didn't properly look after you.
You're family was particularly keen on darker gods but they were to ignorant and didn't properly study the rituals. You were to be the sacrifice or offering. You were afraid and struggled as they sliced your palm open and pressed the blood into the circle. You were afraid and in pain. The ritual was botched but still your blood contorted into the shape of a person and before you knew it the blood god was standing there looking furious. These people had the nerve to try and ask for his blessing after botching his ritual and spilling the blood of an innocent. They clearly hadn't actually studied his teachings.
Technoblade: you botched my ritual and you've just sacrificed an innocent child. Have you even read any of my teachings.
Techno turns his attention to the bleeding and unwell looking child in the floor, their very soul now marked with his godly mark since they've been sacrificed to him. Techno wasn't going to kill them. Techno scoops up the child. He wanted to deal with these people but he couldn't right now. The blood that was spilled from the child spoke to Techno telling him the childs life story, telling Techno everything he needed to know about a person, no one else could hear it since it's one of Technos abilities. Techno dissapear to his realm with the child in his arms.
