The largest part of Duelist Empire Island was, by far, the Free Duel district. This was a massive district, split of 4 different sections, which allowed duelists to duel in 4 different surroundings. The different sections were implemented at insane cost to the owner of the island, who also paid to have cameras watching over almost every inch of the district, instantly ready to be broadcasted or recorded, and to instantly respond to any .
The first section was relatively simple. Its terrain could be summarised entirely as 'dusty'. A wasteland, dry soil and rocks covered the quarter, the illusion of being the last man alive in the desert being broken only by regular huts designed to aid duelists with water and a ride back into town in case they got lost. Dehydration is a danger that every duelist faces if he wants to travel through this quarter.
The second section was a sea- Literally. Consisting of a village entirely on stilts which protruded from the water, this quarter was a home to fishermen and sailors who made a living selling their foods to passing duelists. Wooden and wet, the open areas in this district was made up of waves, water, and the occasional floating boot.
The third section was almost a lava field. Geysers pumped steam up like clockwork, areas around larger geysers being cordoned off, the steam protected by plastic guards. A faint red glow of coals underfoot could almost alarm a passer-by if they didn't know that it was all heavily controlled by heat monitors and an emergency cooling system. More stations were littered across this quarter, offering liquids and cool resting places to thirsty, overheated duelists.
The fourth and final section was effectively a large hill. The height, combined with the flat ground at the top, meant the wind was incredibly strong in this section. Duelists were advised not to take umbrellas or things like that; they would stand no chance in the wind. Birds flew freely in the sky and the warm-yet-windy area of grass was very popular for picnics, for lying down to chat and for passing the time. Dueling too.
Duels took place in all of these areas, and although there was no real difference in the actual duels, the areas provided a variety of places to play in, and pleasant surroundings to walk in.
