Fellspire

Fellspire is a city in Noctis. Though once the largest city in the world and widely considered the capital of Noctis, the core of the city was destroyed, and what is left now surrounds the walled city of Ascendancy.

Creation
The Fellspire was created by Geffuhr, the draconid Immortal of water. The city is named for the first construction, a huge metal tower that the entire city was built around, which was created to house the Infinite Engine. The Engine was Geffuhr's creation, a potent hybrid of High and low magic, which was just as its name promised: a nearly-limitless source of power that provided energy for the entire city. The Infinite Engine has been credited with the Fellspire's rapid growth and prosperity.

The population of Fellspire exploded, and soon it became the largest metropolis in Noctis as people from all around the world came to settle there. It was here that the construction of the Nexus began, and the gap between Equis and Noctis was first bridged.

Destruction
When mortals discovered the secrets of Ascension, many railed against the idea of a single Immortal king ruling over the greatest hub of civilization Noctis had to offer. The Ascendants gathered and approached Geffuhr, who granted them an audience but laughed in their face when they demanded control over the city. This began the War of Ascendancy, which took a huge toll on the Fellspire. Eventually, the Ascendants were able to slay Geffuhr, a feat thought impossible. However, his death caused a tremendous conflagration of magic that wiped out most of the tower that gave the city its name, and reduced the core of the city to ruin.

The Ascendants built Ascendancy in the rubble, a walled city inside of the roughly-circular remains of the city of Fellspire. The remains of the outer city are still in disarray, although they are technically ruled by the Ascendancy Council.

Fellspire
The Fellspire itself was a huge metal tower, most likely the tallest structure in Noctis. The Fellspire contained a great many things, but most interesting among its contents were a multi-floored palace at the top where Geffuhr resided, and the lower chambers (beneath the surface) that housed the Infinite Engine. Part of the Fellspire still remains in the walled city of Ascendancy, but most of it was destroyed during the War of Ascendancy.
