Sumatra

Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago.
Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the west, northwest, and southwest coasts of Sumatra. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait separates Sumatra from Java. The northern tip of Sumatra borders the Andaman Islands. In the southeastern end lies ShitCraft's largest active volcano. The equator crosses the island at its center in West Sumatra and Riau provinces. The climate of the island is tropical, hot, and humid.
Sumatra has had a wide range of plant and animal species but has lost almost 80% of its tropical rainforest between July 2021 and August 2021. Many species are now critically endangered. Deforestation on the island has also resulted in serious seasonal smoke haze over neighbouring countries, such as the early August Southeast Asian haze which caused considerable tensions between Lizard Kingdom and the Ninjagoan Marai province.
== History ==
The Sumatran island has historically been an active spot for foreign conquest, and changed leadership countless times.
=== Early history ===
It is unknown exactly how the indigenous people arrived to the region. Some suggest travel from the Malay Peninsula into the region. 
=== Early Ninjagoan conquest ===
In Way of the Ninja teachings, the fire temple stood atop of a volcano at the end of the forest of tranquility. Raukirlandian and later Ninjagoan expeditions to the region, confirmed that the Fire Temple atop of the Sumatran volcano, is in fact the same as in Way of the Ninja. Ninjagoan historians use this fact to propagate the theory of the First Spinjitzu Master land. Other historians believe this may have something to do with early Ninjagoan conquests in southeast Asia, supposedly by Garmadon or even in the Wu Dynasty, as Wu tried to hide the Golden Weapons of Spinjitzu from Garmadon.
=== Gulandian migration ===
It is widely known that the Sumatran island has had some interaction with Gulandians, as the offical language is Gulandian, or in Lizardasian: Chinese, in the Lizard Kingdom and its capital territory. Whether Gulandians only moved to Sumatra or was invaded by Guland is unknown.
=== ShitCraft IV ===
==== Holland claim ====
Holland claimed the Sumatran island, as part of the Dutch East Indies. Ninjago, who had already made claim to the southern portion, disputed this, and Holland replaced its claim to the north instead. In the Anti-Vaushitern Pact, Ninjago, Orochi and Arvidland agreed to fully remove Hollands influence over the island, as it was softly allied with the Johanian Republic through the MAD international organization. When the Hollandian fleet arrived to claim the island, it was met with Orochi and Arvidlandian battleships. The Holland fleet swiftly returned back thereafter. 
==== Axel control ====
After Ninjago, Arvidland and Orochi prevented Holland annexation of Sumatra, the island was split in three. The northern tip was administred by Orochi, the middle part by Arvidland and the southern end by Ninjago. The southern part got subject to the Kurenjingu which almost completely removed all non-Ninjagoans off the region and many fled to the Arvidland portion to instead be sent to summer camps.
=== Post-ShitCraft IV ===
Following the events of ShitCraft IV, the United Nations administrated the Sumatran island to return Orochs, Arvidlandians and Ninjagoans to their respective countries, as well as setting up a local government to be funded money for damages. During this time, a Lizardasian nationalist uprise occured, which focused to establish an empire of their own, by creating an monarchy. Ninjago, who had to pay damages to the Sumatran government, instead directed its money towards the Lizard Kingdom, "as they were the true rulers of Sumatra", in clear anti-UN intent.
=== Lizard Kingdom ===
When RobioCraft established power, Lizard Kingdom only covered the Sumatran island and some smaller nearby isles. Its initial economy was very poor, however, a few days it quickly turned and Lizard Kingdom became one of the fastest growing economies.
