The air is filled with the sound of clashing swords as tenderfoot and veteran alike hone their skills on the equipment arranged around the training yard. A massive barracks protrudes from the face of the sheer rock wall, its reinforced structure equipped with several ballistas and onagers. Each one is manned by a group of heavily armored archers and guards. High above, a massive twisted horn rests upon a ledge, used to warn the outpost's citizens to run for cover in time of siege by invading forces.
