Key of Three Parts

The Key of Three Parts is a very essential item in Ultima IV, where it is needed to unlock the chamber of the Codex deep within the Abyss. The Key is split in three parts corresponding to the Principles of Truth, Love and Courage.

The Stranger found the three key parts, by venturing into the three altar rooms deep within the dungeons. There, he/she used this fitting Virtue Stones, which represented the Virtues which are based on the principle of the altar, in the correct order to get a key part. Having done this three times, the Stranger put together the Key, before using it in the Abyss.

Later, in Ultima Underworld I, the Key had to be found again, because it was the only way to enter the chamber of virtue with the Slasher of Veils at the bottom of the Abyss. (probably where originally the Codex was stored)
