The Lost Land... A world where time has no meaning - and evil knows no bounds. Torn from a world long gone, the time traveling warrior Turok has found himself thrust into a savage land torn by conflict. An evil overlord known as 'The Campaigner' seeks to shred the fabric of time and rule the universe using an ancient artifact known as 'The Chronoscepter'. The Chronoscepter was shattered thousands of years ago in an effort to keep it from falling into evil hands. The Campaigner has constructed a massive focusing array which he plans to use to magnify and pervert the power of the Chronoscepter in order to shatter the barriers between the ages and rule the universe. Turok has vowed to find the eight pieces of the Chronoscepter spread throughout the Lost Land and put an end to The Campaigner's evil plot... To learn more you must enter the world of Turok
