Some characters are absent during the events of the main story, while an old friend with a new face rules the Underground.

Into this high-tech panoply of despair, one last human falls. Those who climb Mt Ebott are said to never return. You wonder why exactly that was, as you enter the cave.

The hole seems to rush towards you as you fall into the depths of the Earth. ...why is this so familiar?
