The drawing wasn't exactly precise, but Noah couldn't be mistaken about what he was seeing.
The vegetation that had grown there through the years and the influence of the magical beasts had modified that environment, altering the original shape of those lines. Yet, some of them had survived the passage of time and the natural influences, leaving a few distinct images that anyone could see.
Noah wasn't satisfied with just that drawing. He dived back on the ground and began to uproot any plant in the area that featured those basic inscriptions.
More lines appeared as he scanned the terrain. They carried a faint sense of durability, which had mostly faded since the ancestors had probably inscribed them a while back.
Noah could see how they appeared to be part of a large drawing meant to remain hidden under the structure that had occupied that territory.
