In the Old times of the Magus realm before the War between the Gods and the Mortals, Magic was rare and few races understood and used it, some of these races were the Elves that used nature related magic, the Dragons used Bloodline related magic, but the most skilled race in the use of magic was the Fey race.
Fey are a very hidden and vast race, the Fey race had beautiful creatures like the fairies who looked like angels but with butterfly wings and with a godly affinity in magic, some of the Fey were called Hag's, and they were Dark creatures that used Hex energy and Hex curses, all in all Fey creatures belonged to a big family with a good and a bad side.
