A fairly simple logic puzzle.
Label each quadrant with a number and determine which other number they have to their left and right, and who they face. Remember to keep your bearing directed at the mountain.
The two center nations, by definition have to have one symbol in the upper left corner of a shield, and the other center country in the lower right corner of the shield. The other central country will be the reverse of this. If you find two shields like this, those symbols must be the central countries and you can arrange everything else around them.
Frusq isn't in the North East OR the North West quadrants.
Vatria is pretty close to the mountain.
The full locations of the countries and the keyword is found in the next block of text. If you do not wish to be spoiled, please do not continue.
North West: Zakophia North East: Jymuncia South East: Gondalia South West: Frusq West (next to Mountain): Werboxia East (next to Mountain): Vatria
That means the missing emblems in the Frusq shield are as follows: Top Left: anchor, Top Right: dragon, Bottom Right: pair of crossed keys, Bottom Left: double star
The double star emblem belongs to "GONDALIA", which is your keyword.
