CoA Empire of Redania

In a possible outcome of the Witcher 3, Redenia under King Radovid the Stern fights off the invasion of the Empire of Nilfgaard, annexing the whole of the Northern Kingdoms in the process, thus creating a northern Empire. This is my vision of a coat of arms of that Empire. 

The shield reflects the members of the Empire, clockwise from top to bottom:

-Temeria
-Kaedwen
-Aedirn
-Brugge
-Mahakam (all dwarfs got deported to this province where they live under nominal self-rule, but de facto controll by humans)
-Dol Blathana (all elves got deported to this province, where they face the same fate as the dwarves of Mahakam)
-Sodden
-Lyria and Rivia
-Center: Redania
