The Titan's Core is perfectly spherical in shape. It emits a glow depending on the type of Titan. For instance, the Sand Titan's orb shines yellow, while a Rock Titan's orb gives off a dark bronze glow.
The Core is naturally used to power Titans. Based off this discovery, it was bought by the Dwarves after a few rudimentary experiments by the Sand Elves. Any mage is able to move it around using magic when in close proximity to the orb. A Dwarven reactor was built in Stachnias to power the city using the Core and its Crystals once the experiments were complete.
