16th century?

The Synopsis of the subreddit says it takes place in the sixteenth century-like medieval world. Is this an oficial statment? I feel like its around 200-300 years too late. This would even still allow for the traced locations we see to be somewhat similar to what is shown (Lugo and san Xulian de samos)

Havent paid much attention to the details tho, maybe some armors or draining systems wouldnt fit the XIII century

Also fun fact i found out: The geography situation almost seamlessly fits the locations of the story, if not for the description of a nation in the west, it could perfectly take place in the XIII-XIV century in our world
