[PC][2000-2007] RTS game in medeival magic setting with dragons and three different factions

RTS game in medeival magic setting with dragons and three different factions. You could play as one of three factions, and only ONE of tham had dragons as units. Not Warcraft, graphic seemed not very stylized, mark deem atmosphere, fog of war. If I'm not mistaken, you could play as some "hero" characters as well
