Byron spent most of the night centered around the mouth of the Candelaria River where it meets the sea, flying in spiral patterns that gradually extended outward, loop after loop. The more he surveyed the place, the more satisfied he became.
Violet's requirement one for building a shipyard and fortress city: possessing a deep-water river bay, gulf, or harbor, is fulfilled. This area boasts a long deep-water shoreline, capable of accommodating and building large vessels, not to mention wooden sailing ships with a draft of no more than ten meters. Even if future technological upgrades lead to the construction of iron-ribbed wooden-hull ships, Ironclad Warships, or even further to steel Warships, there would be no issue at all. Moreover, the natural barriers of the port could protect the shipyard from storms and other severe maritime weather conditions.
