"Once, the Sanctuary may well have been an epitaph dedicated to the achievements of our civilisation. Now, it has been whittled down by war, neglect, and a lack of purpose, both for the AI that maintains it and the broken refugees that called it home."

The Sanctuary is an immense Type-II spaceborne habitat that was constructed by ancient humans as an experiment in megastructural engineering and later became the last surviving refuge for the survivors of the Human-Forerunner wars.
