There was one major flaw, however, typically lying in their unreplicability—because many of their things were forged over time.
Take the Tower of Dominion as an example. It didn't have ninety-nine floors the moment the Heaven Craft was completed. It only had one floor and was as small as a hut. Then, it grew a floor every hundred years, taking a total of nine thousand nine hundred years up to now. And that wasn't its limit; it was still growing.
Such lengthy growth meant that even Elves, who lived for numerous generations, couldn't experience it fully, let alone those short-lived intelligent beings with a lifespan of merely a century.
The vastness of the inheritance Gaven had received was beyond imagination.
