An Ark!
His mother was proud that he had realized his father’s plans. Even if it was a silly design that he had sketched in his workshop never meant to be built, Noah knew he had to build it. The title of the design was “For Noah, Noah’s Ark.”
And it was exactly that. It was an enormous ark based on the biblical one used to save countless animals during the great flood. Any normal person would have looked at the design and laughed, but Noah took it as a challenge.
