Tjedon
From DALpedia
The walk through the tunnel was long and uneventful. The group took a few turns as the tunnel was actually a network, with a few dead ends for safety, and a few passageways that lead to other roads outside the mountain.
When the group finally reached the outside, they found themselves overlooking the capital city of Tjed, Tjedon, and a winding path down into the valley in which it was built. The city was much larger than the small port town ... The sun was just high enough to pass clear the mountain tops and illuminate the mostly white stone buildings. Thick lush shrubbery and trees surrounded the outskirts of the city, and a classic castle made of the same white stone towered above most of the other structures, far on the northern end.

About
Tjedon is the capital city of Tjed and home to King Henri and his trusted knight Ven. It is the largest city on the island, though dwarfed by the larger cities of the Dark Continent. The castle where the king resides is located in the northern most edge of the city, which is entirely walled. Prairies and a small amount of forest immediately surround the walls, but not much as gargantuan mountains sprout up on all sides a short distance away. Tjedon is known as one of the most breathtaking places in all of Gaian.
