Riska and Feller retired to their rooms, but Suzanna insisted on staying with Anfey. The two entered the underground tunnels following a few dwarves. The main entrance to the tunnels was slanted and facing upwards, and took a sharp turn downwards after about thirty feet. Anfey thought it might have been built this way to prevent flooding and keep excess rain from pooling in the tunnels. There could be other reasons that Anfey did not know. The dwarves and the gnomes obviously knew better than he did.
