These and pictures are used as emblems and flags of islands of the planet. The first picture can be found on the shields of Ipsilon knights. The second is situated on the banners and cannons in Torblynd. The third and the forth are used as banners in Valfross( the forth is used only on recent screenshot of developers. It is situated on the tower).
