Ërdin (lit. ‘earth-home’, Elven) is a planet-sized celestial body, created and populated with life by Boccob, the greater deity of magic, although sometimes Ërdin may also refer to the demiplane inside which the world is contained. Ërdin has two satellites, a magical burning ‘sun’-satellite called Fürdel (lit. ‘fire-moon’, Elven) and a pale rocky moon called Ërdel (lit. ‘earth-moon’, Elven). It is contained within a small spherical demiplane whose boundaries form Boccob’s Veil, a potent god-level abjuration which blocks all extraplanar beings from entering the plane of Ërdin unless summoned by a native, and also causes all of Ërdin’s natives to be born immune to most forms of resurrection magic. Ërdin is generally described in academic literature as containing four “continents”—Liangdin to the east, Tynwë to the northwest, and Komwë to the south, with the three Dead Islands classed as one continent of Novdin despite their scattered state.
Radiological and divination evidence suggest that Ërdin is approximately four to six thousand years old. The clergy of Boccob claim that He has revealed the precise date of creation to them as midnight on Novanna 1st, 3989 years ago (what would coincide with the first day of the year 2001 in the Common Year of Oerth, if the people of Ërdin were generally aware of Oerth’s existence); with no particular better specific date to work off of, this date is traditionally used as the starting point of the Calendar of Ërdin.
Ërdin possesses a very limited diversity of life, as is typical for an artificial world seeded with life based upon creatures from preexisting worlds; Boccob has kept the biosphere fairly simple, with only a dozen or so thousand macroscopic species. However, a great many of these species are highly magical (or at least, intelligent and potentially magical) in nature, and the most ambitious—or most brutal—of these species have forged great cultures and unified or conquered civilizations across the face of the globe—in particular, the human Kingdom (and later Empire) of Tyne, which ruled most of the land and sea of Tynwë from the mid-eighteenth to the late twenty-seventh centuries, devastated the Dragon Empire, and scorched Komwë’s green fields and jungles, before succumbing to internal corruption and external invasion by migrating hordes of elf barbarians.
