Reimteyja

Reimteyja is a post-game location, located at the north-west of Sargad. It is inspired by Iceland.
Reimteyja is located in the northeast of the mainland of Sargad. It is an island with an even colder climate, but there is still a plain. In the northeast of the island, we find the Geyser Sandur, famous for its ravine crossed by the ocean. The Litrófjökull volcano, in the center, hides a considerable secret, protected by Fire and Rock type Pokémon... 
Reimteyja comes from the Icelandic "reimt", meaning "scary", and "eyja", meaning "island".
==== Draugavík ====
The biggest city on the island. The player will stay there during this part of the game, with Ylia and Sven's family. In this town there is a museum full of artifacts that are mysteriously disappearing...
Draugavík comes from "draugur", which means "ghost" in Icelandic. Inspired by Reykjavík.
==== Ektodúr ====
The second largest town in Reimteyja.
Ektodúr comes from "ectoplasm". Inspired by Eskifjörður.
==== Skugghólmur ====
The smallest town on the island. Harbor village, there is not much to see there, except the annual Frillish and Jellicent migration.
Skugghólmur comes from "skuggi", which means "shadow" in Icelandic. Inspired by Stykkishólmur.
==== Mount Litrófjökull ====
The volcano located in the center of Reimteyja. The artifacts of the Draugavík museum end up strangely at its bottom. There are many Fire- and Rock-type Pokémon living there. Another Pokémon seems to be their leader...
Litrófjökull comes from litróf, which means "spectre" in Icelandic. Inspired by the Eyjafjöll volcano, covered by the Eyjafjallajökull glacier.
==== Lake Skelfulón ====
The only lake in Reimteyja. It is located south of the volcano, and thus is heated by it. Many people come here to relax and do thermal cures among the snowy plains of the island.
