Tharn Gate (or Tharn-Gate) is a fortified outpost and wall complex located at the only navigable pass through the eastern escarpment into Sanctuary Vale. Built directly into the surrounding rock, it spans 6.5 miles in width and serves as both a controlled entry point and a strategic observation and logistics hub. The site is managed by the Council of Stone and maintains continuous operational readiness.
Geography
The wall spans a natural break in the escarpment, with uneven cliffs rising on both sides and broken ground leading southward into the Fractured Wedge. The structure is built of iron-bound basalt blocks set in interlocking tiers. Watch platforms are integrated into the wall’s outer face, and internal tunnels allow movement between segments. Northbound terrain is flat but wind-exposed, while southern terrain is unstable and layered.
History
Tharn-Gate was established after early crossings through the escarpment proved difficult to monitor, prompting the Council of Stone to construct a permanent barrier. The outpost grew around the wall as convoy flow increased, eventually incorporating waystation functions and traveler processing facilities.
Functions and Features
- Wall Span – The main structure, extending 6.5 miles, includes reinforced gates and elevated walkways.
- Entry Hold – Administrative chamber where travelers are logged, inspected, and cleared for descent into the Vale.
- Watch Bastions – Armored towers spaced along the wall for personnel rotation, signaling, and survey.
- South Ledge Post – A separate observation tier positioned on the edge of the broken terrain to monitor approach traffic.
Culture and Ritual
Daily activity is regulated by a fixed operational schedule. Communication is limited to formal channels, and non-essential passage is discouraged. Residents include Stonewardens, logistical clerks, and maintenance crews. Temporary housing is available for caravan travelers and Vale-bound expeditions.
Defenses and Watch
Tharn-Gate is maintained at alert status year-round. Each segment of the wall is staffed with trained personnel, and defensive tools include reinforced gate seals, observation instruments, and close-range signal devices. In the event of breach or instability, fallback orders direct personnel to seal internal gates and reroute through Mar-Thal.
Threats and Dangers
The primary risks are geological: terrain collapse, wind erosion, and structural pressure fluctuations within the lower foundations. Surface crossings are prohibited during surge seasons. Unauthorized entry attempts are rare but logged.
