Vox In Excelso

Klingon cadet Jay-Den Kraag learns that his family may have been killed in a starship crash on their way to a refugee camp. During the Burn, Qo'noS and the Klingon Empire were destroyed, leaving the Klingons an endangered species facing extinction. As the cadets engage in a series of debates on the topic, Admiral Vance enlists Chancellor Ake's help to propose a solution to Klingon General Obel Wochak, an ex-lover of hers: asylum on Faan Alpha, a potential new homeworld in Federation space with conditions virtually identical to Qo'noS. However, the Klingons refuse to take what they see as charity and per tradition will only accept the planet via conquest. Jay-Den struggles with the memories of his brother Thar's death and his family's subsequent abandonment of Jay-Den before Cadet Master Thok gives him a new perspective on things.
