The Elf region is the region where the Elf characters start. You can visit this region only if you are Elf or if you reach level 30. The region is composed of 6 areas.
The first area is Arthlan (your starting city), then Grove of the Ancients, Windswept Wetlands, Lake Slari, Luna Prairie and Abyssal Glade. Each zone is harder than the one before.
