The City of Wonders circa 1550 was the greatest city in the Holy Country, and one of the greatest cities in the world. With a population of 50,000 souls it was probably about the same size as Nochet (remember this is before the Opening), and occupied much of Loon Island. The city was connected to the each of the Sixths by magical bridges, but most people traveled there by boat – remember that few ports along the Mirrorsea Bay are more than about 50 km from the City of Wonders.
Belintar maintained a number of galleys to ferry around dignitaries, guests, and officials. These galleys were without sails (“winds are only treacherous), but many of the fishing boats and merchant ships do have sails.
Greg drew up a schematic of the city some years back. This is conceptual and ideal (as many of his notes often were), but it is entirely possible that Belintar was able to pull of this near perfection. Gods and spirits dwelled in the City of Wonders alongside mortals and powerful magical entities like the Reef Master or the Tide Lord. So you might go to the Golden Anchor for a drink and meet a visiting Triton or a son of the Storm Bull who has come here from Stormwalk Mountain.
In many ways, the city it resembles the most is Glamour. The City of Wonders was a place where the mundane world crossed over into the Gods World. But when Belintar disappeared in 1616, the City of Wonders was mostly removed from this world, and remained only as a ghostly remnant. And after 1624, Harrek destroyed and pillaged that remnant (with perhaps the aid of your player characters!) and now it is entirely gone from this world.
The disappearance of the City of Wonders is one of those sad melancholic things like a half-remembered dream after you wake up. You wish you could return to it, but can barely recall it.
Imagine the myriad thousands gathered to watch the tournaments and to take part in its splendours. The diversity, the magic – heck, Jolly Fat God threw his parties. Jolly Fat God often visited the City of Wonders! As did Mister Bondaru, a noted Lhankor Mhy sage who served as a court philosopher for Belintar in the 1550s. His specialty was “The Physical Body and its Ethereal Attributes,” and even wrote a paper on the subject. He was also very knowledgeable about the God Learners.
