I stand on the rim of a massive ring of chromed metal easily the size a troll could fit through. Many other rings run in a line from were I stand, their openings laid end to end to form a kind of gleaming silver backbone arcing gracefully into the endless darkness all around me. Gleaming branches, twisting and spiky, jut from it like the ribs of an unknown ancient beast that breathed its last here in some bygone age, its bleached and gleaming bones lying upon a forgotten shore. All else is a dark void, with only faint glimmers of light in the depths.
