Etrenank is the capital city of the Sacred Empire of Solaris. It is located in the very center of the flying artificial nation and is suspended upside-down by artificial gravity systems. In Solaris, the surface hangs overhead and the sky is beneath the player's feet. The center piece of the capital is the massive Imperial Palace where Emperor Cain and Karellen reside. A large entertainment district known as Arbot/Arabot/Araboth Plaza is located just before the bridge leading to the palace.
