In ancient times gargoyles were used to guard buildings from evil spirits. They were just statues made from stone to stand and guard eternally. At some time a few wizards considered the possibility of enchanting these statues and putting them to some real use. After years and years of experimentations, the first living gargoyle was born out of a small stone statue. The method quickly spread from a mage to another until it was common for wizards to have gargoyles guarding their studies. It was only a few centuries ago when the horrible accident (that created the race of gargoyles) happened. A powerful magus had summoned a demon, asked some arcane questions from it and then banished it away.
But something went wrong with the banishment and the spirit entity of the demon was trapped in a gargoyle. The magical spirit that kept the gargoyle 'alive' was quickly subdued by the powerful demon. However in the process the spirit of the demon collided with the magical forces keeping the gargoyles alive. The spirit of the demon was spread among all the gargoyles made with the spell. This was too much for the demon's spirit and it perished. For the gargoyles it was enough to set them free from their eternal slavery under the spells that had controlled them. Some of the gargoyles fought their owners, some negotiated their freedom. Many gargoyles died during their rebellion for freedom, but in the end they won it. These days many gargoyles roam the lands, searching for gargoyles still in slavery, hoping to free them. Most gargoyles however still do the same thing they were born to: guarding people from evil spirits. Most other races fear gargoyles for their violent past and their frightening outlook, but some adventuring parties seek the help of gargoyles for their great physical powers.
