Krennla was a city on the planet Qo'noS, made up of several districts, including Kenta District and Baldi'maj District. During the reign of Chancellor Kravokh, Krennla was an industrial center which benefited from the economic boom of that era. In the decades that followed, businesses declined and Krennla became largely destitute. The estate of the House of Varnak was near Krennla, and when Eral, daughter of B'Ettak was expelled from the House, she was forced to live in the streets of Krennla. Krennla was attacked by the Borg in 2381, sustaining heavy casualties. (ST - Destiny novel: Lost Souls)
