The Civilisation of the Ancients
The First Ones. The Lost Tribes. The Ancients. Whatever you call them, they were the original inhabitants of what we now know as the Sea of Thieves.
Signs of their civilisation can be found all over the place: cave paintings, potteries, and other artefacts. They built temples, altars — places that were important to them. The Ancients had ships and even a few pirates. There were also artisans and sculptors, philosophers and painters. Their currency was possibly the Ancient Coin, a rare coin emblazoned with what appears to be a skull.
They were an intelligent and creative community, they charted star constellations, told stories, and became aware of the magic that the Sea of Thieves offered. As they mastered the use of magic, they created specially imbued relics such as the Shroudbreaker. They have also been claimed to have used Kraken Ink to see the future, much like how the Order of Souls use Kraken Ink in recent times.
It is unknown if they were all one united people, or if they lived in different tribes. The monolithic statues found on Tribute Peak at least suggest that there were ten key figures in their society.
