Though they are technically not connected, Oasis Island is still considered a region of Gems Continent due to their close proximity. One of the least inhabited regions on all of Sarvannia, Oasis Island is by no means ignored or avoided. It is actually a very common place for the wizards of this continent to harvest fruits, vegetables, and herbs they otherwise could not obtain. The reason these delicacies even exist is because of the circle of snow-covered mountains that line its entire coast.
These mountains are so tall and thick it shelters a pocket of hot humid air within the valley at its center. This allows liquid fresh water to exist on and near the surface, thereby fueling the tropical forest that gives this island its name. The unusually hot humid air as well as its intermediate small rivers and streams are fueled by the multiple geysers that pepper this tropical oasis. The only reason it is typically not inhabited is because it allows the unique plant life here to grow naturally without any interference. Over time, this has proven to produce the richest and most nutrient-dense fruits, vegetables, and herbs possible from this small island.
