World of Yullaara
A race of the Third People, the Elohim that lived in Archiope and worshipped the pantheons of Archos. The Mercaedans wrote the first books of magic and created the ley lines that all arcane magic flows from. The Mercaedans formed magic into structures that form the basic infrastructure that all arcane spells are built off of. The Mercaedans are known as the fathers of Wizardry. All schools of arcane magic are based on the books of magic they originally wrote. All arcane spells used by wizards today are either adaptions, rediscoveries or clever manipulations of the spells they originally created.
With their books of magic the Mercaedans taught their mortal creations, the Maenus how to use magic. The majority of Mercaedans lived in Meridia and many of the ruins of their temples and cities can be found there along with powerful artifacts, legends of lost books of magic and other treasures from their long lost age.
