Guardian's Grave

The Guardian's Grave is the resting place of Sophia, an Arisen who had Selene as her own pawn. You encounter them both during the quest Witch Hunt. Later in the game, if you go back to the grave, you will find a slate which can be turned into an Arisen's Bond, a ring that has the power to choose who your love interest will be during Deny Salvation. Only one of the chests near the grave respawns, but there is another chest behind the giant tree right behind the grave.
