But a new evil has appeared, willing to bend them under its will, like the older gods used to do. The Argons, a race coming from the subterranean world started to wreak havoc on the territories of the different races. Their only goal now seems to be the utter domination of the surface world.
The Argons first attacks were so strong that none of the surface dwellers were able to repel Tera Gold. Therefore the Humans decided to forge an alliance named the "Valkyon Federation" with the Castanics, the Amani, the Poporis, the Barakas and the High Elves, the main factions of the world. This coalition was created with the goal of preventing the Argons from conquering the civilized races of the surface world.
Players of Tera Gold enter this universe in a critical period for the Federation. Tensions are emerging among the members of the federation while the Argons slowly gain more ground. Many of the gods from Arborea's early days are rising again, meddling in mortal affairs, settling old scores, and trying to regain the divine power they lost at the end of the Divine War(Tera online Gold).
