What is BG?
(More information on the Basic Game can be found in the LoK section on the left-hand side.)
BG stands for the Basic Game. The island of Kesmai was the first land implemented, followed by Leng. Leng was later removed and replaced with the land of Axe Glacier. Leng was then later added back in, followed by the addition of Oakvael.
All new players start out in the Basic Game on the Kesmai town docks.
Legends of Kesmai for the most part is based off of the Basic Game, except for the Underkingdom, which was created specifically for LoK.
