The Hiigaran Landfall took place in 9510 GSY, when the Kushan Mothership and her Mothership Fleet returned the Kushan to Hiigara, the planet they were exiled from 4,000 years prior. In addition to the Mothership's crew, 550,000 Kushan Sleepers were awakened from their cryogenic sleep in the Cryo Trays. The Landfall was hard on the Sleepers because they didn't have the long journey to cope with the loss of Kharak and their families. The Hiigaran Landfall begins the new dating system established by Diamid as the moment when the first Kushan set foot on Hiigara. The new dating system is referred to as AHL - After Hiigaran Landfall.
