Time Tunnels

You are out for a walk one day when you find yourself lost in a remote region of the forest. Instinctively you head towards a stream which you follow to to the mouth of a hidden cave. It is very dark inside and you decide it is best to go back downstream. Suddenly and evil looking old man orders you to enter the cave or he will kill you. He wants you to go inside the cave and find a golden ring which once belonged to him. He gives you a lamp and pushes you inside and says, "Do not linger child and heed the warnings of the Guardians!" Frightened, you turn on the lamp and your adventures in the Time Tunnels begins.
