The Flammenherz Kingdom's Capital City.
Within this place that can be considered a massive strategical fortress of a city, with one of its sides, the west, being the only thing that is exposed to open danger as its north and east are covered by a nearby mountain range, and the south leads to an open sea, this is one of the hardest places to attack in a war among all the capital cities of the nearby kingdoms, something that makes other sovereigns, kings and queens alike, jealous of such strategically placed capital city.
Of course, while it makes it easier to defend it like this, said defense only applies for a similar level of power between the kingdom and the opposing party should someone attack them, as everyone in this world knows the absolute rule when the war already involves high caliber mages and martial artists.
