Zaros ordered Zaroth to be built where today is the green dragon's den in the Wilderness do defend the northern cities, such as Ghorrock. Its foundations were dug in the first day of the Hundredth year of the Second Age, when the Wilderness was still green. Ten years later the flag was placed in the top of the sentry tower, and that meant it was finished. Marveled with its beauty, Zaros ordered that a skillful artist made a painting of the fortress.
