They spent the night in the forest and in the morning found that the clouds had cleared leaving a pale blue and bitterly cold sky. Half an hour after breaking camp the innobol trees thinned out and they came all at once to a high bluff overlooking the river Osynder. It took Asanka's breath away. Vast and slow moving it looked more like a lake than a river as it flowed slowly but inexorably north. "Yonder lies the Beacon of Ulon", Crinomu said, but he did not need to point for the island they were seeking was obvious. A small building occupied a flat plateau in the centre and Asanka judged that the "spire" Hirrilow had spoken of was a long thin pole rising from its roof. Three large dishes were clustered round the beacon and a long stone bridge gave access to the island. "We must backtrack a little", Crinomu said. "We have come to the river too far to the west and need to work our way down from these heights to reach the bridge."
