Breifine

Should invaders from the other realm manage to penetrate the periphery of Hibernia’s frontier, the defenders can take some solace in the fact that Breifine’s geography provides several natural funnels and choke points.

The many hills and valleys here are also inhabited by all manner of magical creatures, which the people of Hibernia know to avoid but invaders might not be so lucky, weakening themselves before managing to reach the relics they so desire.
