The north and the west and the south are good hunting ground, but it is forbidden to go east. It is forbidden to go to any of the Dead Places except to search for metal and then he who touches the metal must be a priest or the son of a priest. Afterwards, both the man and the metal must be purified. These are the rules and the laws; they are well made. It is forbidden to cross the great river and look upon the place that was the Place of the Gods — this is most strictly forbidden. We do not even say its name though we know its name. It is there that spirits live, and demons — it is there that there are the ashes of the Great Burning. These things are forbidden — they have been forbidden since the beginning of time.
