Lezio was raised by his mother, a wood elf, and his father, a nord. He is an only child but had a great relationship with his parents. They lived in a secluded area in the forest. Lezio's mom taught him how to shoot a bow when he was 7, and he practiced it daily. She also taught him how to stalk his prey successfully. His father, a blacksmith, taught him how to hunt, forge quality armor, and use a sword. He would often go hunting with his mother or stay home with his father to craft quality armor or improve his swordsmanship. He was never really educated, but he learned how to survive in the wilderness. In addition to learning about forging armor and weapons, his dad also taught him how to craft and properly use a tent, while his mom taught him how to hunt and live in the wilderness.

Lezio's parents also teamed up to keep the peace throughout the land by killing bandits and other people that deserved to die. Around age 16, his parents took him on his first raid mission. Lezio's parents didn't want him to get hurt and took him on a very easy mission. They would only allow him to use his bow and if any bandits got close, he was to run home. Lezio's archery skills, even at such a young age, were remarkable. Their first raid was successful and Lezio found the experience to be absolutely exhilarating. From then on, Lezio always went with his parents on their raiding missions instead of being left at home.

His dad trained him even more in one-handed combat so he could finally come face-to-face with the bandits. A little over a year after his first raid, Lezio was finally cleared by his parents to fight the bandits one-on-one. Another easy raid went well, and he found one-handed combat equally as fun as archery.

He continued raiding bandits with his parents for many years. They taught him how to fight fairly, and honor the dead by never stealing their equipment or personal belongings. His parents also taught him that potions were very bad for him and that he was not to perform any type of magic as it is very dangerous. Lezio had the utmost respect for his parents and obeyed their wishes.

Most importantly, his parents taught him that some people, and only those people, deserve to die. No matter their race, gender, age, or religion, some people only wanted to hurt others for selfish gain, and those people deserved to die.

After years of successful raids, something went horribly wrong. Lezio and his parents only raid at night, allowing them to use the darkness as cover and have an element of surprise. As Lezio's dad began to sneak into the back gate, Lezio's mom fired an arrow at a scout perched on a tower. All the bandit's attention was directed to their fallen bandit. Lezio fired a few arrows at the group of bandits before sneaking up on a bandit and slitting his throat with his dagger. He disappeared back into the shadows as his dad joined the fight, flanking the bandits. His mom continued firing arrows from the woods and dropping a couple of the bandits. Lezio joined the fight with his father, and they killed the remaining bandits. As they always do, they checked the rest of the camp for any survivors, making sure they wouldn't be followed home. After the search was complete, they headed for home. Little did they know, they were being watched.

This bandit camp had two scouts. One in a tower, and one in a nearby tree, wearing brown and green to blend in with the tree. After Lezio and his family were out of sight, the scout climbed down the tree and lit it on fire, signaling to a nearby camp of bandits that there were enemies nearby. This camp of about a dozen bandits followed Lezio and his family back to their house. Lezio and his parents put out the fire in the fireplace and turned in for the night. About an hour later, Lezio woke up and had to go to the bathroom. He went out the back door and into the woods to relieve himself. When he returned, he found the back door swung wide open. This was very strange, as he always good at shutting the door behind him when he leaves. As he approached the door, he noticed a smear of blood on the doorknob. Knowing something was wrong, Lezio grabbed the sword that his family keeps by the door and called out for his parents. He heard no answer. He crept through his house and investigated every room for signs of a struggle. There was nothing out of the ordinary in the main room of his house. He moved to the next room, his room. His blankets were thrown on his floor and there were slits through his floorboards and hay where somebody obviously ran a sword through. Lezio was very afraid something happened to his parents. He moved to his parents room and he was shocked and what he found. His mother lay lifeless in the bed, her throat slit and the bed stained with blood. He went over to his dad's side of the bed and found his dad dead on the floor with an arrow in his neck and a stab wound from a dagger in his chest. Next to him on the floor was a dead person he didn't recognize, but dressed in studded armor like a bandit. Lezio was devastated and dropped to his knees in agony. Just as he dropped to his knees, he heard the glass of the window behind him breaking, as something shot right though it. To his horror, it was an arrow that was lit on fire.

The arrow immediately engulfed his parent's wardrobe in flames. Lezio got off the floor and ran out of the room. As he did so, another flaming arrow was shot through the main room in his house, catching the table on fire. Since the house was made of wood. Lezio knew he needed to get out of there. He turned to run into his room to get his bow and sword, but his room was already engulfed in flames that quickly spread from his parent's room. He sprinted out of the main room and burst through the back door to try to track down the bandits that had killed his parents. He ran around to the front of his house but couldn't see anybody around. Only some footprints in the dirt. He turned around to see his whole house engulfed in flames and he knew he couldn't salvage anything from the fire. He then set off to track down the bandits that had killed his parents.
