From The Aywas Wiki
The Arctic is was a special Explore area released on March 26th, 2011 just after Aywas moved to a new server. Unlike the standard Explore areas, there are no requirements to enter the Arctic nor Quests or Monsters. The Arctic is more like a special seasonal explore area, but it does not have a limited availability duration. Many Ay species in the Arctic are not found wild anywhere else currently, such as Arions, Sors, Finx, Kernals, and Cheves. The Merchants are also unique in that they do not sell the usual assortment of items, but Fossils which can be exchanged at the Museum. The Arctic Treasure Chests also contain only Fossils and no standard items. This area is now an Adventure only area.
