The Stone Chamber is a quest in Might & Magic: Heroes Online.
As the final barrier to the tomb, Al-Kadhir lets the hero battle the Guardian of Grief. Like the Guardian of Silence, this one also recognizes the hero is not one of the Shantiri and refuses the Dreamer of Life to be awakened. The Guardian, in the first stage of battle, is a hero, that can cast abilities that limit the enemy creatures' movement. Some of the creatures can act every three rounds, but until then, they are sleeping, with their resistances against melee and ranged attacks increased. In the second stage, the Guardian, as a boss, is accompanied with three stone griffins (which are also sleeping). With the guardian's defeat, the Dreamer of Life appears.
