Kulma Narrows was an inhabited area on the planet Naboo.
Behind the scenes
Jason Fry, writer of The Essential Guide to Warfare, eventually cut any mentioning of Kulma Narrows in the final product. The location was later made canonical in the StarWars.com blog post Star Wars: The Essential Guide to Warfare: Author's Cut, Part 6 — Showdown at Naboo.
