Fell-Q'ac'watt, meaning "The City of the Great Tower," is the largest city of the Elkari and the center of their civilization. It is a city of a single extremely tall brass and bronze tower which extends past the rare clouds of El-Duram. From the outside, it looks to be a wide tower of metal and pipes. But on the inside, it is a fully realized city, split into various floors.
Fell-Q'ac'watt was the largest of the vessels which the Elkari used to flee El-Bayir in the wake of the Great Flood. It was converted, piece by piece, into a large tower-like structure and combined with surface-mined brass and bronze following the landing of the Elkari.
