Sandalwood Box

The Sandalwood Box is a magically sealed box that can only be opened by a few. It is in the possession of Lord British, who uses it to store his most prized possessions. It appears in Ultima V and Ultima IX,.

Description
Before commencing his journey, Lord British stored his Orb of the Moons in the box, hiding it behind a secret wall in his bedroom. The Avatar found and took possession of it by playing "Stones" on the harpsichord in his Lord's chambers. Later, in Dungeon Doom, Lord British opened the box to use the Orb of the Moons to escape from the dungeon through a red moongate.

In Ultima IX, the Sandalwood Box contained the Ankh of Spirituality, and again had to be opened by playing the song, "Stones".

Trivia

 * An attempt to use the Sandalwood Box in Ultima V results in the Avatar asking, "How?"
 * Not having the box or not admitting having it to Lord British (regardless how insane that is) results in a non-standard game over, with the heroes being trapped with Lord British, most likely waiting to starve to death. It's made worse by how little clues there are about the box.

Ultima V: Lazarus

 * It is easy to lose the box forever in Ultima V: Lazarus. Saduj steals the box from the Avatar if in the party before fleeing. If the party is caught in the Palace of Blackthorn, Lord Blackthorn takes it away from the Avatar and murders a companion.
