(imp assuming we start outside the school)
A black portal opened up in front of the school gates. Mark stepped out of it and the portal closed. He was now trapped here until he could get better control of his abilities. hereditarily gaining these powers were a disadvantage. His control was very weak when he first relies he had these. Fear was a huge factor In keeping his powers out of control. He seemed a bit off, coming from the realm of the underworld. Being so hot down there he was usually almost butt naked. But on earth where it is hot people wear t-shirts and shorts, so that's what his dad gave him to wear. He walked through the gates ready to begin the journey to better control his powers.
