egio Media, known as the hranice among the Czech-speaking covenfolk, is where most covenfolk live and work. Manifesting a fourth magnitude magical aura, it is a place of wonder and vibrant sensation. Within the hranice, the embankment is revealed as an oval ring wall of stone, timber, and rammed earth construction. The space between the wall and the boundary is cleared of overgrowth and planted with clover and dandelions. About twenty-five paces from the wall, the edges of the boundary are filled with old-growth oak and hornbeam forest, although attempts to journey into the forest inevitably, somehow, lead back toward the wall. The ring wall is intact and well-maintained, with a walk atop the earthen fill and timber stairs ascending the inner wooden wall in places.

Two gates open through the wall, one at each end of the oval. One gate opens north toward the manor and the mill; the other south toward the river. The southern gate is of iron-bound timber set on thick fir posts with iron hinges. Enclosed timber super-structures top each gate, with firing embrasures covering the approaches. The gates open inwards, towards a smooth paved ramp cut into the side of the ridge. The gates are operated via a continuous loop pulley and winch mechanism set on each side of the gate (one per gate valve), and are locked by a huge swivel timber that is operated via another pulley and winch mechanism from inside the gate tower.

The northern gate is more heavily trafficked, and is more impressive. The gateway is formed by two massive granite statues of aurochs rampant, with their forelegs extended to meet overhead, forming the arch of the gate. The horns of the aurochs are polished obsidian, arcing upwards from the rearing heads of the aurochs. The stone of the statues, and the flanking gate towers, is a rich green-gray granite with scattered blue-black speckling. Iron-bound gate valves like those at the southern gate enclose the arch, and are operated by a similar mechanism.

Within the walls are numerous buildings, including several impressive major structures. A broad cobbled street leads straight as an arrow from the gate toward a large three-story octagonal Aula (great hall) of log and timber construction rising above the surrounding buildings, about 550 paces from the gate. To the left, rising just inside the ring wall at a point even with the Aula, is a large three-story wooden tower. Wooden ramps ascend in clockwise fashion to the top of the tower, which is a broad, flat mooring platform for a wonderous flying ship, the Aethranavis. The Aethranavis is a modified Baltic cog, flat-bottomed and wide of beam, which somehow floats in mid-air, tethered to the mooring platform (kotviště, in the local parlance).

The area near the northern gate is the Bráně čtvrt (Gate quarter), which is filled with noisy, bustling activity. As one passes through the gate, to the right one hears the barking of the dogs in the kennels (smečka psu), down a curving street, Ulice Kovářu (street of smiths), which follows the western wall. To the left of the gate, Ulice Kotviště (street of the mooring) curves around the inside of the eastern wall toward the mooring tower. Straight ahead is Siroká Ulice, the broad cobbled street that leads up the center of the ridge to the towering Aula. Stables and barracks line the avenue to either side as one moves toward the Aula, transitioning to fenced pastures and then to densely packed two-story townhomes along side streets stretching to the left and right as one enters the Aula čtvrt (Great Hall quarter).

The northernmost side streets are Ulice Mečonoši (streets of the blade-bearers). Closer to the Aula, Ulice Stráží (street of the sentries) leads off to the left/east; across from it to the right/west is Ulice Kopiniki (street of the lancers). East from the Aula, Ulice Kotviště (street of the mooring), leads toward the mooring tower before turning sharply left/north along the inside of the wall, back towards the gate quarter.

West of the Aula is Ulice Mlýnský (mill street), which leads from the western entrance of the Aula to the hranice mlýnský (regio mill), which sits near the western wall, with an undershot mill wheel rotating between the wall and the mill building. The mill wheel appears to be turned by water from a shallow stream that runs just inside the wall from the south, the stream flows north from the mill along a narrow canal beside Ulice Kovářu (street of smiths), before turning west and flowing underneath the wall, eventually emptying into the Dyje River.

The Aula proper is surrounded by cobbled streets and a five-foot high hedge in a square, with breaks at each of the four streets leading to the Aula. At each of the four streets, broad steps ascend from the street to a circumambulatory balcony on the first above-ground floor. Within the hedged area are a few structures separate from the Aula, but connected to it via walkways. A small shelter southwest of the Aula covers a stone stairway leading down into the northern end of a huge subterranean cavern, glittering with countless small quartz crystals embedded into the ceiling and walls of mystically fused rock.  Two large granary towers of solid conjured basalt occupy the cavern; simple wooden storage platforms line the cavern walls, with barrels, sacks, and baskets of various foodstuffs, all as fresh as the day they were placed there.

South of the Aula, Siroká Ulice continues arrow-straight down the center of the covenant, towards a massive obelisk of dark green banded malachite that towers over the southern section of the covenant, corresponding to the position of the white megalith outside the hranice. Between the Aula and the obelisk (sloup in local dialect) various residences sit along the avenue, with shallowly terraced gardens and fields to either side between the residences and the wall. Just as with the gardens outside the hranice, the quality and abundance of the produce seems astounding. Onions, garlic, cucumbers, melons, radishes, turnips, beets, parsnips, carrots, beans, peas, cabbages, and various herbs and greens grow profusely within the beneficial climate inside the hranice.

Midway between the Aula and the obelisk Siroká Ulice broadens into the Náměstí, a diamond-shaped plaza more than fifty paces across, where a second cobbled street, Ulice Náměstí, crosses from east to west.  A fountain spouts water into a large pool at the center of the Náměstí, at the geometric center of the Foedus.  A magical aqueduct supplies water to the fountain from a river, which is then distributed via tiled underground channels to several locations throughout the hranice. 

Several large stone and brick buildings face the Náměstí from its sides between the broad streets.  To the northwest is the lázeňský or balneum, a bathhouse with a common bathing area and separate steam rooms.  On the northeast is the Vilicium, or offices of the Vilicus and other officials of the Foedus; Vilicus quarters are on the upper floor.  To the southwest is the krčma, a large tavern that serves beer and ale, and occasionally mead and wine; along with simple food (stew, roasted fowl or meat pies).  On the southeast side is the pekárna, a communal bakery with six large ovens for public use.

South of the Náměstí, Siroká Ulice continues toward the obelisk, with various townhomes and crafters' workshops. The Siroká Ulice ends just short of the Sloup (obelisk), at a cleared space about ten paces in radius around the obelisk, bounded by a low stone wall. A chimarae (Obluda) sometimes squats on top of the obelisk, unmoving but watchful. To the west of the obelisk, near the western wall, lies the Hranice Alvarium (apiary), with dozens of scattered beehives. South of the Sloup the space within the walls is filled with neat rows of fruit-bearing trees, with a simple dirt track leading to the Reky Brána (river gate) at the southern apex of the ring wall.

Outside the wall to the south is the Reka čtvrt (River quarter). The regio boundary on this level is an oval approximately 360 paces across by 2200 paces long, and extends just into the waters of the Dyje River at this point. A small cottage with a few outbuildings sit on built-up mounds between the wall and the river.
