Demetrius was born in Moonlight Falls to Oberon and Titania, King and Queen of the Kingdom of Faerie. His mother and sister loved him from the get go, but his father despised him for being a normal human Sim and not a Fairy. Even though he was the firstborn son and rightful heir of the Kingdom, his father refused to relinquish it to him.
Demetrius never stopped trying to impress his father. He stayed out of trouble, got perfect grades in school. Despite his mother's protests, Oberon had Demetrius shipped off to Fort Starch Military School to finish his elementary and high school education.
Demetrius was miserable at Fort Starch and begged his father to let him come home, but it was obvious that he was there for the long run.
Once Demetrius graduated from Fort Starch, he decided he wasn't going to return home and take any more of Oberon's abuse. Instead, he hitchhiked across SimNation to Bridgeport, where he managed to get a tiny apartment, which he shared with three other people: Buster Round, Lenny Shutter, and Mick Situp. He began moonlighting as a mixologist at Eugi's, a local sports bar. It was here that he met his future wife, a young architect named Helena Frederick.
After two years of steady dating, they were married in a small ceremony. When Helena found out she was pregnant with their first child, the couple agreed that Bridgeport wasn't the best place to start a family. They said goodbye to their friends and made the move to the sleepy little town of Ferryport Landing.
Demetrius spoke to his father for the first time in ten years shortly after his son Puck was born. Oberon had learned that his grandson was a Fairy and decided that he would be made the new heir.
- Demetrius is named after the character from Shakespeare's "A Midsummer Night's Dream".
