As the runes gifted to early settlers by the Gods were exhausted, the Fremennik unearthed a new mineral 'Rune Essence' and used it to create new runes, thus the art of Runecrafting was born.

Soon after the Fremennik Clans began infighting. Many Fremennik believe it to be a privilege of the gods to create magic, with some labelling Runecrafting as "heresy" and believe that the gods will punish mortals for stealing "their" power. One of the tribes 'The Moon Clan', were attacked by the more traditionalist Fremennik for their use of man-made runes and left for the Lunar Isle, taking the secrets of Runecrafting with them leaving the remaining tribes to forget the now ancient use of magics.

In the years since then, other nations learnt of the Rune Essence and conducted their own experiments in Runecrafting.

Through devoted study and experimentation you have rediscovered the ancient arts of the Fremennik, developing magical runes which can enhance your martial prowess in extraordinary ways. By inscribing these runes onto your weapons and equipment you channel the powers of the Anima Mundi to give you powerful abilities.
