Construction beginning/end
The full period of construction and preparation of the Gates of Vast.
While Vestergil held his reasons close to his chest, he forced the people of the Isles to assist him in the construction of massive gates which would sit between Logrvast and Gelvast. Due to their size, it is assumed that some divine influence must have been required to construct it as well as for their functionality. While it was designed to allow several portions to open so that small fleets could enter or exit, they were rarely to be used. By and large, it was intended to open from end to end. During this time, Vestergil would attempt to make reparations for the great destruction he brought to the isles, with little avail. He ensured that they could function independently of him, though they would eventually benefit from his divine grace.
