Adding rooms to Cal's "Choose your own adventure" game…

I’m spending some of the afternoon adding rooms to Cal’s “Choose your own adventure” game. Rather than introduce you to the game from the beginning, where it’s experienced a fair amount of ‘game-rot’, I’m going to introduce it to you from the point at which I started adding rooms – lost in the foliage, you have decided to scour the ground for a tunnel. Finding two, you have chosen the one with the humming noise and the faint green light…. Now choose your own adventure…. [REQUEST – please try and keep the plot in character and mood – it would be interesting to see how this might emerge…]
