Runestone (Warcraft II)

The Runestone was an ancient monolith erected by the Elven Druids and inscribed with powerful runes of protection and warding. The Runestone, seized by Gul'dan and his Ogres, was eventually hewn into slates that were then used to construct the Altars of Storms. The Elves, knowing that their sacred artifact had been defiled to create the Ogre-Magi, have sworn to destroy all of the unholy Altars across the kingdom.
