This sea current streams from Kryzus to the Orne Harbour. Ships can then quickly reach the boreal coasts of the next island Freuzanyu, or keep sailing toward the Spray Bay and leave Insularyuu's coasts to cross the ocean. The Tjars current is so strong that no ship can go back up this stream, so they have to find another water path, either at the Boréas of Freuzanyu, or at the Suttas of Insularyuu, crossing the Mirrors' Sea.
Favorite place of Sileya, it spreads across the Boréas coast of the island. It is also the place you will meet the Dracquints in the first gamebook.
