Crystal Currency

Defined by the World Bank as a single shard of High or Low-density crystal, containing a standardised (1 LDM or 1 HDM) volume of mana. A shard of LDM resembles a fingerling crystal akin to a 3cm hexagonal pencil. The appearance of LDM currency is exemplified by its semi-opaque state. Comparatively, a shard of HDM is transparent and without blemish, measuring 5 CM. Certification is overseen by a cooperation between the Towers and a local agency (Bank of China, for example). The volume of crystals in circulation is often controlled on the Frontier.
