Leskya Nui

Leskya Nui was once a cold, urban island in the Southern Matoran Universe, home to around 2000 Matoran. It is now a hot, radioactive and desolate island covered in smoke and uninhabitable by most species.

History
Leskya Nui was created at the same time as the rest of the universe and populated with Matoran of all elements. They built metallic, urban communities and lived in relative peace.

At some point, four new Matoran (four of the Dozen Venturers) arrived and fit in with the population.

When the Brotherhood of Makuta heard of the island, they immediately targeted it, as it was home to many Fe- and Fa-Matoran. The island came under attack by their forces, and in response, Vandir, Hatar, a Su-Matoran, and four other Matoran were transformed into Toa to defend the island. Eventually, the Brotherhood led a very devastating attack, using powerful weapons of mass destruction that caused great fires to break out and released high levels of radiation. It was by Vandir's orders that most of the inhabitants escaped on vessels, but after the Makuta began targeting their ships, only he, Hatar, and around twenty Matoran made it out alive. They eventually landed on Powai Nui.

Some parts of the island broke off and/or sank, and the constant heat, fire, smoke and radiation left over from the weapons used made the island close to uninhabitable, save for several species of hazardous, microscopic Rahi mutated from the attack. All tracse of other live has been eradicated or mutated into grotesque beasts.

Characteristics
Before it's demise, Leskya Nui was a wintery island, mostly surrounded by firm ice, which some inhabitants built their civilizations on. The mainland was populated with cold-resistant plants and many flying Rahi, some of which were domesticated. The weather was always stormy, providing fluffy, powdery snow that was the catalyst for many snowsport events. The island also had magnetic properties, causing colorful lights to appear in the sky some nights, a form of Aurora Borealis. Nights during which these lights appeared were calculated and marked on calendars so that celebrations could be held to watch them. Many Fa-Matoran became very wealthy just from predicting these lights, including Hatar.

After the attacks, Leskya Nui became exceedingly hot, ridding it of all of the ice and plants. Certain areas of the island became so hot that there were neverending fires. A majority of the Rahi species were killed off, and the ones that survived were mutated into awful creatures. Without proper protection, the average Toa would survive for around twelve hours before succumbing to the harsh environment and perishing. However, beings wielding the element of Fire or Plasma are more likely to last much longer. The waters surrounding the island are polluted and toxic, making a perfect home for hazardous, flesh-eating microscopic creatures. The lights appearing during the night are no longer visible from the island, blocked by the smog.

Trivia

 * Leskya Nui will likely be revisited in the future, possiblt in some sort of serial.
 * The characterisics of Leskya Nui's weather before the attack are based off of text on some Utah lisence plates, claiming the US state has the "Greatest snow on earth".
 * Some of the characteristics of Leskya Nui in it's current state are based off of Earth's surface during the Precambrian Period.
