Durance

A Durance is a Forerunner device designed to contain the extracted memories and personality impressions of an individual.

Durances were a key element of Forerunner funeral proceedings. Upon the the death of a Forerunner, their last memories and mental patterns were stored inside a time-locked Durance. The Durance and a bit of plasma from the immolation of the body were then presented to the closest family members of the deceased. Durances had a half-life of a million years. Their resting places were closely guarded by the family, such that the violation of a Durance was considered sacrilege.

The Promethean Knights' essences are also contained in a form of Durance, one of which, named by the Covenant as the "Didact's Gift", was recovered and studied by the UNSC during the Second Battle of Requiem.
