Crystals

The crystals are how the gods get their powers. But, Teroh, an evil mastermind from the Frid Empire, made replicas of the crystals. Those were used to power the Sterben Lords, like Mal Tod and Mal Vendettis.

The Gods of Asten
There are only three gods of Asten. Zephyrus, Lymphus, and Sinistre. Each has their own crystal which gives them their power.

Zephyrus, the god of air, wind, thunder, lightning, and tornadoes, has a grayish amethyst in his possession.

Lymphus, the god of water, the Seven Seas, earthquakes, hurricanes, tsunamis, and waterspouts, has a blue sapphire in his possession.

Sinistre, the god of fire, the Underworld, and death, has a red ruby in his possession.
