Arimpheans were the original inhabitants of Odiem. They spoke the arimphean language, which allowed them to communicate directly with the gods
During the Rift Era, the arimpheans had to choose to align with either Oekhan or Phrenia. Those who aligned with Okekhan became known as humans, and those who aligned with Phrenia became known as elves
Arimphean is also the name used to describe the humanoid races of Odiem, as they all descended from the original arimphean population. The arimphean races are: Human, Elf, Dagrin and Thaloran.
