Amber

Amber is an actress at the Royal Theatre and also Shamino's girlfriend.

After hearing about her in a banter between Shamino and Iolo in Ultima VII, the Avatar visited the theatre to meet her personally. Amber admitted that that her role as Sherry the Mouse was her first role as actress and while she liked the theatre, she despised the play itself and her role as a mouse, claiming she should be playing a queen. She also griped about having to learn Sherry's children stories.

She then went on to embarrass Shamino in front of his friends with a very public display of affection, admitting that she knew he would be able to retire from adventuring life.

Since Shamino wasn't seen in the castle in Ultima Underworld II, it is most likely that he'd spend the night at Amber's house, when the disaster befell the castle.
