Four sisters of masks

A battle older than history...As the elf king El-Melech, lord of Lunas Enoch, stood gazing at his endless forest, he recalled the first age of dark when evil ruled the world of Sastion. Those were days of his own epic struggles and the last alliance among elves, dwarves, and humans that bound the dark lord and brought peace. Now the earth is again crying with the sounds of war, and messengers from distant corners of the empire of Lun bring news of horrors unleashed by the returning evil of evils and his servants. El-Melech, the human emperor Corvelin, the dwarven king Rundor, and all other leaders ally together for the good of the earth. Only the four sisters of Masks can save them, their magic is the last hope.
