Sandalwood Box

The Sandalwood Box is a magically sealed box, that can only be opened by few. It is in the possession of Lord British, and he uses it to store important Items.

Before Ultima V, Lord British stored his Orb of the Moons in the Box, hiding it behind a secret wall. The Avatar found it after playing Stones on the harpsicord, taking the Box with him/her. Later, in dungeon Doom, Lord British opened it to use the Orb of the Moons to escape from the dungeon with a red Moongate.

In the non-canon plot of Ultima IX, the Sandalwood Box contained the Ankh of Spirituality, and again had to be opened with the song Stones.

Trivia

 * An attempt to Use the Sandalwood Box in Ultima V results in the Avatar asking: "How?".
 * It is easy to screw up the game by losing the Box forever in the Lazarus version of Ultima V. Saduj steals the Box from the Avatar, if in party, before making a run for it. While if the party is caught in Castle Blackthorn, Blackthorn takes it away from the Avatar (while a companion is cut apart).
