The Elemental Sleepers are a set of four characters in Might and Magic V: Darkside of Xeen. They are robotic servants of the Ancients. After Sheltem was defeated, the dragon pharaoh asked the Defenders of Xeen to awaken them so that the unification ceremony could be carried out.
The party must travel to the skyroad and enter the Plane of Air, Earth, Fire, and Water to awaken the Air Sleeper, Earth Sleeper, Fire Sleeper, and Water Sleeper, respectively. Each of them is guarded by a monster (a whirlwind, earth blaster, tidal terror, and fire blower). When the guardian is defeated, the Elemental Sleeper will tell the party that they are awake and that their "confidence is at 100%. Grunfeld field generator is active and reports 100% confidence."
If the party goes to see the Elemental Sleepers before receiving the quest from the dragon pharaoh, they will tell the party that they can only be awoken by a chosen one.
