The Demonsword Universe canon has a number of places in the timeline that should be filled in with books eventually. These detail characters and events that are canonical to the setting. The lists below are not final or official, and represent only currently underway or planned stories.
* Immortal Dawn (The book of Deus Exterra) - 1st Transition (1st to 2nd Age). A man from Terra, who takes on the alias Deus, meets up with his past. As hints start to surface that Terra is looking for a way to reach him, he goes around warning them that the world he left is one not likely to be friendly. But when the gates between the worlds open, what he sees is not at all familiar, and more hostile than he was expecting...
* Spendthrift of Chaos (The book of Domino Effect) - 1st Age/Terra. At the dawn of industrial holography, a technology poised to change the world, a man fed up with politics decides to start his own holography-based nation in the sky. But when legislation the world over threatens to put control over the most powerful of all technologies, against which there is no defense, in the hands of only a chosen few, he makes the riskiest gamble in human history, before or since: he releases it to everyone, everywhere, no matter their purpose.
