I throw myself into the tunnel before me with reckless abandon, my haste increased by the enormous gust of wind propelling me in. Down and down I fall, trying to cling to the edges, which are moist and slippery.
After what feels like an eternity, I emerge into a large chamber, filled with networks of interconnecting tubes. I look around in wonder, pondering where to cause damage and destruction first. But time moves quickly in this vast space; before long I am travelling back up the tunnel, heading towards the light, billowing out of the entrance.
And I evaporate gently.
