The Pure Stones are receptacles for energy, specifically the energy that created the Megalith, as well binding the guardian to the stones.
Description[]
These stones were created by the Wizards of Yan, and were used alongside the Spell of Binding to seal the Megalith away. As the Defenders' mission was to rebind the Megalith, they used a device called the Key to locate the stones which were spread across the realm.
The Megalith's energy was contained in the four stones, and have the strength to overpower those who touch the stones, such as Mel. Because of this, the Pure Stones were kept in a Yan-Altas Container that absorbed the stones' power.
When the Defenders destroyed the Machine of Binding to allow the Megalith to go free, the Pure Stones were destroyed.
Locations[]
The Dako Pure Stone was hidden away in a mountain, and the Defenders were given directions by the shaman. The Megalith's energy in the stone manipulated its surroundings, reforming the rocks into a maze system. It also caused the Defenders to see hallucinations and be unable to cast their stones, but this ceased when the stone was placed in the Yan-Altas Container. When Mel first touched the stone, the Megalith's energy overtook her, placing her into a coma that was only cured by the Vitus Stone.
The Ogama Pure Stone was hidden in the Monastery of Gata-Sum, which is found along the Bay of Tantar in the province of Infinor. The temple sank underwater once the area flooded when the Spell of Binding was cast. Mel had a dream of the temple, and they used their Aqua Stones to reach the temple. The stone was tucked away in a narrow crevice, and when it was knocked to the ground the monster guarding the stone awakened.
The Yan Pure Stone was being carried by a Gata-Shin Monk through the mountains when he was attacked by the Gisli. The stone fell down a crevasse and was buried in snow, hidden until the Defenders reversed the polarity of the Machine of Binding and it was drawn to them. It was then teleported to another location when the polarity was returned. Adam was able to find the stone again and gave it to Brackus.
The Yin Pure Stone was hidden in a temple in the Yothma Woods. Bo managed to find the stone, but fell to his doom as the temple began to collapse. He and the stone were then drawn to the Machine of Binding when the Defenders reversed the polarity. It was then teleported to Callisto when the polarity was returned. The Doom Hunter attached the stone to its tail and hid itself underground, and was guarded by the Dark Stalkers below Callisto.
