Isle V, later dubbed "Tiāntáng de yáolán" or Heaven's Cradle, was a planet located in Union of Progressive Peoples space in the Frontier's Weyland Isles Sector. Decades prior to 2186, Heaven's Cradle was terraformed and colonized by the Jùtóu Combine; as of that year, it featured an Earth–like climate with clear blue skies, and was the site of two colonies. In 2186, Heaven's Cradle was attacked during a spate of biological attacks known as the Border Bombings, and was bombarded with a mysterious alien pathogen. Amid the resulting Xenomorph outbreak, a lone colonist was able to send out a transmission warning others away. The message was intercepted by the Righteous Fury, a warship used by the Xenomorph–hunting paramilitary organization dubbed the Jackals; however, the unit arrived too late to offer any quantifiable assistance.
