Durance

A Durance was a type of Forerunner memory storage device. Upon the the death of a Forerunner, the individual's last memories and mental patterns were stored inside a 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.
