Ankh Amulet

The Metal Ankh is a item of power and virtue.

The Stranger found it at the circle of stones in Ultima IV, and it was the key to entering the Quest of the Avatar. The Avatar kept it and used it in Ultima V, together with the Codex Coin, to first call the Moongate and then to scare away the Shadowlords, wearing it around the neck during the game.

The Ankh wasn't seen in Ultima VI, but its fate was clear when it reappeared in Ultima VII in the Museum, clearly labeled. It is not clear if the Ankh in Ultima IX is meant to be the same one.

The Ankh as a Trinket
When Ultima IV was shipped, every box of the original release included the Ankh from the game. It was made from metal, Aluminium, and could be worn on a chain like a Ankh Amulet. The Dragon Edition of Ultima IX also shipped with a metal ankh very similar to that from Ultima IV.
