Crystal of Duplicity

Crystal on display inside the Castle Britannia throne room.

Crystal of Duplicity is a crystal which Nystul used to copy the land in Felucca onto Trammel. Minax also used the crystal to be in both Felucca and Trammel. Lord British took it from Minax when she infiltrated Trammel. Ricardo's research that has been revealed during the In the Shadow of Virtue - Lost and Found Part 3 quest identified the crystal's location as the throne room inside the Castle Britannia. Sherry the Mouse found the crystal at the vault in the begining of the In the Shadow of Virtue event cycle and the crystal is retrieved using the words of power from Ricardo's research. The Crystal was on display inside the Castle Britannia throne room before it was stolen during an attack by Daemon Scouts and Blackrock golems.
