Forbaku is reportedly a "lost island" off of the coast of Greece, similar to legends such as Atlantis and Mu. Alternate names include Forbacks and less commonly, Phorbulaxx.
Reports put the story of Du Sig alone at 10,000 years prior to the modern age, but this may be an embellishment. History before Du Sig is known but scarce, and included such heroes as Shere and Kride du Gran. These stories are collected in a tome known as the Noga Kard.
Forbaku had been under the control of many leaders, but none are indicated by name before Coulagemo.
