Brion

Brion is the keeper of the big Orrery and the observatory in Moonglow in Ultima VII. He also is a collector of rare things (which people see as trash), and the twin brother of Nelson.

When the Avatar visited Brion, he/she got a lot of information about the Astronomical Alignment which would be very important. Brion was also very pleased to show the Avatar his collection of rare things, remembering that he wanted to build an Orrery Viewer so that the orrery can be watched from anywhere, but he needed a crystal. The Avatar helped him to find one, and Brion gave him/her the Viewer after he had finished it.

Later on the quest, it was Brion who put the Avatar on the right track, towards the Lycaeum, where information about the island of Ambrosia would be found.

Through it wasn't mentioned, the death of his twin brother Nelson at the hands of Patterson a year later must have devastated him.

Trivia

 * The is a interesting love triangle going on, with Brion being part of it. Zelda has a crush on Nelson, but confuses him with Brion. Brion admits, he has no feelings for Zelda, but Nelson has. Quite interesting, eh?
