The legend says that for thousands of years trolls and humans lived together in peace and harmony. They shared all lands of Sklotopolis together. There were no fights, no wars and no murdering. But sadly as we all know this did not last forever. Around 600 years before the year 0 an evil troll human hybrid named Zavikus was trying to achieve the total dominance over all islands trying to wipe out all human beings in the process.
His army was feared more than everything there was to be scared about. Bigger than everything we know. Stronger than the toughest dragons we thought. He overwhelmed every outpost, town and village on Sklotopolis EXCEPT FOR a group of three brave mages and their followers which were holding their ground in a small village on the Novus island. Through the power of 3 mystic gems they managed to defeat Zavikus and his army. They banished him to an unknown location from which he should never return. Atleast they thought so. It is believed that he will return one day trying to gather all 3 gems and destroy human kind for ever.
Nobody knows what happend to the 3 mystic gems. Some say they got destroyed during the final fight. Others say they are still hidden somewhere in the lands of Sklo. Many tried to find them. Nobody ever returned.
