The Heritage Council consisted of Hapan nobles, specifically AlGray and Galney of the Duchas, who formed an alliance with the Five Worlds throughout the Second Galactic Civil War. Their objective involved maintaining the Hapes Consortium's autonomy from the Galactic Alliance by removing Queen Mother Tenel Ka from power and assassinating the Chume'da Allana. With this intention, they employed the bounty hunter Aurra Sing and assaulted the Hapan Royal Navy utilizing their fleet. Ultimately, the coup was unsuccessful, leading to the capture or death of the majority of the Heritage Council members.
