Grendelsbane Station was a Royal Manticoran Navy duty station and shipyard that was established in the Grendelsbane System some time prior to 1905 PD. The Station was supported by the second largest Manticoran fleet yard, expanding to over 50,000 Manticoran personnel in 1919 PD. Its shipyards and other orbital facilities were destroyed with nuclear devices in 1919 PD during the Havenite Operation Thunderbolt. The loss of the system was the final blow that led Michael Janvier, Baron High Ridge, to resign from the office of prime minister. (HH3, HH10)
