The Olympus valley was once known Zardoz dome. The inhabitants were scientist survivors that prepared for the great war and continued their advanced studies until they created a super computer called “the Oracle”. The Oracle found a way to make his protected people immortal and the scientist ordered the Oracle to do so and hide itself so that no one could destroy the oracle and kill them. Many centuries passed and a traveler was able to damaged the Oracle and many immortals died in the process of repairing it. Now there are only 12 that have more power than the old ones and have mortals as slaves. The technology that makes them immortal and powerful is so advanced that duplicated arcane powers of 100 points of Mana. [MOVIE: Zardoz]
The Oracle evolved to become Ambrosia, a sentient PL9 computer that is keeping the Ambrosians alive.
