Peculiarities sighted in the quarry and waterways: - Leysprings of various sizes, including a particularly impressive one due south of the Temple of the Blessed Mantle. - Hydrothermal vents, implying a source of immense pressure beneath the quarry. - Impressive pipework spreading magic throughout the various seer structures. - Numerous sunken architectural components. - A variety of aquatic creatures that seem to be thriving despite the high concentration of magic in the water. Even my senses are challenged here.
