Arda

Arda, colloquially called Earth by the locals, is a planet, perhaps the most noteworthy part of most versions of Eä. If a universe has Arda in it, it's probably considered a version of Eä. Arda is also called Gaea, Gaia, Terra, and Tellus by certain smartypants to appease the goddess by that name who embodies the earth of Earth (which, if you remember, is the English endonym of Arda). Arda's primary and most influential species is humanity, as the two species more intelligent and powerful than them who share the planet, mice and dolphins are smart enough to stay away from Ardan politics. Arda is the third planet in the Zynamon 5 system in the Zynamonian galaxy.
