The architecture of the Arconians is one of the most complex, beautiful, and effective achievements of their civilization: this is clearly visible in the impregnable and majestic walls that surround their land.

If the maps don't reveal anything, here are some initial thoughts:
1) Fencer (either from Hinkalia or Tangion)
2) Swordsman from Deit
3) Mage (forbidden or Eihornian)
4) Commander-merchant from Hinkalia (yes, with a skill in seduction), a pure support character.
