Vnals were sentient organic constructs created by the Vaathkree. Also known as "life-towns", vnals were domed cities used by off-world visitors to the planet Vaathkree. Vnals were partially organic, and were also marvels of metallurgy and engineering. As a result, vnals were partially alive and able to communicate with their inhabitants. While they were comfortable for brief periods, most visitors were unnerved by the prospect of sleeping inside a living, breathing, building.
