Gandidan was a child at Benden Weyr during the Ninth Pass. He was a friend of Felessan.
When Jaxom and Felessan were missing one day at Benden Weyr, Manora asked Gandidan if he knew where they were. He admitted seeing them going toward the back corridors. After Manora remembered that she'd been missing used glows again, and heard that Ramoth was upset, she deduced that the boys had gone to look at the eggs.
