I realise that last post was a bit weak so here's a cheeky bonus:

There is a place in Jesmond dene, off the track and overgrown. Great slabs of rock fence in a rough clearing with logs placed as seating in the middle. They all face towards the same spot: a crack in the cliff face, overgrown with moss and vines and so dark that the blackness seems to spill out and creep up the walls.

It is a doorway. A doorway to anywhere, everywhere. No one knows how the destination is chosen. Preparing is impossible. The doorway can lead to the most glorious destination imaginable. It can lead directly into a sleeper's nightmare. It could lead to the bottom of the ocean or to the edge of space. It could lead to a cafe just down the road.

Enter at your own risk.
