One thing you must realise is that there is no such thing as pure iron/steel these days. Iron/steel isn't nearly as strong now as it was in medieval times. However, with that said, iron in early medieval times was so soft you could hack right through a helm with a sword and leave a nice lil mark on the skull (depending on the grade of iron used on the sword and the helm, ofcaurse). After many hundreds of years of fine tuning, however, the only use the sword had was to puncture the plate. That was very difficult, however, since the grade of steel was so hard... only blunt instruments and weighted axes had any use against plate armor in later medieval times. Makes me wonder why rapiers were so popular then and why less people wore plate (Other than it's obsene costs... a nice suit of armor would cost as much as a nice lexus does now... and a kings suit would be as much as a rols royce).
The city of Nausopol is built on stilts. Lots of very sturdy stilts and butresses, of course, because it rises about five hundred feet from the ocean. Even the most terrific of storms is only heard in the city as a distant cacophony of blasts as waves strike the solid stonework fathoms below. It has never been attacked because of its isolation and impregnability.
It's not a place for the faint-hearted: vertigo and sea-sickness are not desirable traits. But when you are standing in the middle of the city there is no way you could tell that you were standing above an ocean, separated only by a gulf of air and a few stones.
A thousand steps lead down from Nausopol to the floating docks. These docks are pitch-coated wooden and can be raised by winches during squalls. Trade with other cities and countries is good: Nausopol is built over a sunken atoll whose minerals are still mined by divers, and it was from this that it originally derived its wealth.
But the principal method of getting to and from the city is by riding the giant sea-eagles which have been captured and bred for that very reason.
