Constructs are constructions of power, putting together various known Powers in new ways, allowing said powers to be used across Shadow more easily, even by those without the skills usually needed to use them. The art of Construct creation was little-known to most of the Royal Family of Amber before the Annadil Crisis, especially the design of freewilled sapient ones. However, this changed as the Crisis progressed, and several were built or converted to the cause of Amber.
At the time of Through A Mirror Darkly, the following Constructs were known to exist or had existed:
- Miki's Trump Conservatory : Built out in Shadow for Miki? to work on his musical trump experiments and to access its power remotely. Totalled in the experiment that freed him from Outsider Control.
- Gabrielle : Created by Corrine after repairing the Fire Pattern of Ember so that she could access the Fire Demi-Jewel's powers remotely, this construct soon was treated as Corrine's daughter.
- Morgenstern : Built by Annadil using Shaft's Flawed Demi-Jewel of Fire, this construct quickly decided that serving Shaft was a better deal than being smashed into a zillion pieces.
- Kafuin : Built by Corrine and Gideon of Avalon at the Keep of the Five Worlds, so as to properly power the Elder Sign that seals off the Fount Of Power.
