Spyglass

The Spyglass is found in Ultima V. It is used to watch the night sky with the other eight planets of the Britannian Solar System and eventual Comets. It is the only way to predict a Shadowlord attack on the cities, thus staying out of trouble with these mighty creatures. Using it during the day, under roofs or in caves isn't possible.

Going after several clues, the Avatar asked Seggallion in Farthing for the Spyglass. Receiving it after correctly answering a question about the planets, the Avatar had now a very useful tool at hand. Watching the sky at night with it, he/she could see the eight planets, each representing a city of Britannia. Three comets symbolized the Shadowlords. Until the Shadowlords were vanquished, a comet over a planet said, that the corresponding city was under Shadowlord attack.

With all three Shadowlords destroyed, the Spyglass lost its usefulness to the Avatar.

Trivia

 * Another Spyglass is on the roof over Lord British's room in his castle. Sadly, it is fixed to the ground, and can't be taken with you. The same goes for several others found on building tops.


 * Telescopes in later Ultimas were strangely only useful to look at the ground.
