Burial vault

A vault beneath Camelot Castle houses a number of sarcophagi, each containing the remains of a deceased noble.

Among the dead in the burial vault was Tristan de Bois, whose remains were reanimated by Nimueh so that de Bois could take his revenge on Uther Pendragon. (Excalibur)

It is almost certain that the remains of Igraine de Bois reside in this burial vault as well.
