Titan Quest: Immortal Throne Dev Diary

The expansion begins in front of a temple to Apollo above the city of Rhodes, where Zeus has chosen to return you to the earth. You don't take more than a few steps when a ghostlike figure appears to you out of thin air. It is the shade of Tiresias, greatest of all seers. He tells you that terrible things are going on below, in the realm of Hades, the land of the dead. So you set off on a journey to find an entrance to the underworld. And when you finally get there, you discover there are a lot of things that aren't right, not to mention a massive army poised to invade the surface world!
