Arronus VII

Arronus VII was a planet located along the Federation-Klingon border, and was well known for its mineral deposits.

In the first year of James T. Kirk's command of the USS Enterprise, the starship visited the planet on a survey mission. A small survey party consisting of Lieutenant Lee Kelso and Ensign Beltre beamed down, and found that a squad of Klingons were also conducting a survey mission. Outmanned, Kelso and Beltre fled into the jungle, and Beltre was injured. However, Kelso kept fighting and keeping the Klingons at bay, in time for Captain Kirk and Lieutenant Commander Spock to arrive with reinforcements. (TOS novel: My Brother's Keeper: "Constitution").
