Asgard

Asgard (アースガルズ) was one of the nine worlds of YGGDRASIL.

Background
The World Tree YGGDRASIL had countless leaves, but then a gigantic monster appeared which devoured these leaves, causing them to fall one after the other, until only nine were left. These nine leaves were the previous incarnations of the Nine Worlds, particularly Asgard. However, the leaf-eating monster continued its advance to the point where it seeks to devour the leaf representing Asgard. This was the backstory upon which the players adventured into the world of Asgard in order to protect it.

Asgard was one of the realms where many players of the humanoid and demi-human races mainly resided in. By entering Asgard, players of the heteromorphic races are known to have disadvantages placed on them when faced by non-heteromorphic players.

The world was described to be ridiculously huge, and there were many places within it which were difficult to explore. For instance, there were many areas which required the use of special equipment along with a proper strategy and the determination in order to delve into its hard-to-find dungeons that drop valuable Data Crystals.

In the world of Asgard, there are extremely high-end crops like Platinum++ Asgard Pekoe which can be harvested there at specific times within specific seasons. While the seasons tend to change over the course of time, so do the the variety of crops that differed from it during each harvest specifically. Other crops that can be harvested from Asgard include the Asgard Beet.

Layout
Within Asgard, things became more dangerous the further one went from the center of its world. In addition to the wandering monsters, the very terrain itself became a hazard for players to explore.

Features
A developer-sanctioned tournament was held in this world where one could become a World Champion and acquired a special powerful equipment awarded as the winner's price for exclusive use with that class. Only one player with the World Champion job class was allow to exist in Asgard. There is also just one guild base in this world that contains 3000 levels of NPC Data Storage which is highest amount by far available.
