I've created the heraldry for the five major kingdoms in the game: Immater, Barivain, Maletar, Rhidhelmark, and Daeyshir. These are shown below. Typically the heraldry will be found on banners in the capital cities and worn by royal guards and the like. Also this is the crest of ruling family members and will be seen on tabards and shields of each royal family member. Variations of the heraldy does exist for certain extended royal families and those knights who branch out further and further from the tree or have a desire for their own uniqueness.
Additional peoples and areas have their own heraldy, banners and devices like the dwarves, goblins and orcs, as well as many more among the various minor lords and knights throughout the lands. I will add more as the game progresses, especially for the ones that are encountered more frequently. I just wanted to ensure the main kingdoms were on display first.
Kingdom Heraldry
Minor Heraldry
Here is additional heraldry from some of the minor powers or smaller kingdoms in the game. In order we have: the dwarven hold of Stormfist, the dwarven hold of Steadfast, the destroyed aquatic elven kingdom of Laeyshel, the destroyed minor human kingdom of the Greyson Isles, and the self-proclaimed Pirate-King of the Golden Archipelago.
