Etherious crystals. These are crystals that are made up of raw ether. These crystals are not natural and are crafted from the raw ether that flows through all brings. most crystals are small and take a very long time to make. Stronger ether wielders can make quick work of these as they can afford to loose more. There are many uses for raw ether crystals. Crystals can be consumed to temporarily boost ones abilities. Two or more crystals can also be refined in to a “mirror” and “linked” to create a line of communication over any distance, working theory is that the light and vibrations are transmitted across the plane of etherious linking the two.
Sage / Seeker Stones – these exceedingly rare stones are said to have origins from etherious itself. The stones have the ability to attune the ether in the wielders body to the plane of etherious. One of each type of sage stone exists for each type of ether that manifests. The stones seem to “seek out” the sages that wield them.
