District I is one of the two Southern Oceanic Districts, and part of the country of Corinth. It's the smaller of the two Districts, but larger than The Borough. It's located in the former Australian Northern Territory.
District I came into existence after the catastrophic flood and subsequent World War which ended life on Earth as it had been. When sea levels began to quickly rise and the world's nations engaged in a devastating World War which ravaged the planet, a large ship/submarine known as The Shuttle, evacuated many people from Europe and North America. They were hidden underwater for nearly an entire year before surfacing and seeking refuge on Australia.
While Australia had been heavily affected by the rising oceans and the World War, most of the land was intact and safe from any radiation poisoning or any other related issues.
About 692,000 people had been saved, including those who had survived the chaos, and those aboard The Shuttle. In just a matter of years a new government had been established and the continent/country was renamed Corinth. At the time, only the heavily fortified city named The Borough was established.
Around 2 ADD, some of Corinth's best scientists discovered Panem, the other newly forged nation. Panem's 13 Districts inspired Corinth's Districts I and II. They continued to monitor Panem without contacting them, watching the other country fall into war and into oppression. They continued to watch as the Hunger Games was founded and President Snow rose to power.
They remained under cover and stayed quiet for many years, watching as the Far East Districts emerged, and their subsequent war with Panem, especially over District 14.
District I is responsible for all things technological, such as weaponry, transportation, technology, medicine, and all new innovative ideas.
Like the rest of the country, surfing is very popular in District I. Fishing, scuba diving, swimming, and camping are also highly popular.
