The Age of D'ni is the name of Earth according to the D'ni people. The Age was Written by Ri'neref to house the group of Ronay refugees from Garternay. The name was said to mean "new hope" in the D'ni language.
As a location, D'ni refers to the underground Cavern where the D'ni people built the D'ni city. It has been suggested that the cavern was inhabited by the native creatures the D'ni called Bahro, until the D'ni enslaved them in the process of claiming the cavern for themselves.
The other parts of the Age of D'ni outside the Cavern taken into consideration, is the Surface, although during the millennia they thrived, the D'ni were mostly ignorant about what lay on the Surface of their home, and the native humans.
