Extend the Story - Add a Room

You stand at the entrance to a large dungeon, a cave in fact. You peer into the depths of the cave. Pitch dark. And very steep. Once you enter there, you may most likely never get out. But you know you must enter. You have to redeem the Sword. You just have to.

You take one last look around you at the countryside before plunging into the depths.

Level 1.
Life force Green.

And what would lie beyond it?

The right door
