In the 23rd century, Masaba was home to a primitive humanoid civilization, the Masabans-or, as they refer to themselves-"(The Village of) The Cat People." The planet had once been much more technologically advanced, with ruins of great computer-controlled installations hidden in Masaba's wilderness.
In the 2260s, the Starfleet starship Enterprise was stranded near Masaba, and a landing party visited this world searching for dilithium. After finding their way, having made contact with the Masaban tribal chief, then a medicine man, the crew avoid shooting plants and swamp beasts, obtain a repellent against Masaban blood worms, and enter a ruin using an artifact known as the Eye of Kakos as a key. After overcoming a puzzle of alien symbols, the crew activate a powerful computer that allows them access to a store of raw dilithium. (TOS video game: 25th Anniversary)
