Chala IV was a planet located in 24th century Federation space, somewhere in the galaxy's Alpha or Beta Quadrants, the fourth planet in orbit of the Chala star system.
History and specifics[]
By the 2350s decade, Chala IV was the site of a Federation outpost. Due to an attack, the base was defended by fightercraft in a dogfight. With the urgency of the situation, cadet pilots were called up to fly the mission, including Sam Redbay and Will Riker. They had thought they were going to die that day.
