From the introduction:
Asterland is an invented fantasy setting within the fictional world called Jera.

User summary:
Asterland on the World of Jera is a fantasy setting developed originally for Advanced Dungeons & Dragons. The setting is not tightly coupled to that game, however, and could be easily adapted to any fantasy game system.
The setting is presented as a series of HTML pages with these major divisions: Introduction, Setting, Culture & People, Places, History, and Races & Creatures. In addition, a Gamemaster Resources page includes several system-agnostic adventures (primarily narrative elements), setting-specific fiction, and additional tools.
