does anyone have any infomation on this please?

I'm playing right now, it's a bit boring, its a one single dungeon which expands, it's a prison where the rock is digged, and so, the prisoners of Varus open new spaces. To advance you must clean the dungeon of mosters and treasures, interact with the friendly prisoners and visit Helga often to hear rumors, which will point you to the right direction. To hear this rumors from Helga is scential in order to advance in the game.
