The Clutch of Verthandi
A masterpiece of engineering and solar magic, Daedal’s Sun is a relic of the Dwarven Age and one of the wonders of Dragonhelm. A massive artificial sun suspended above the royal palace, this artifact would turn from dark to light in accordance with the real sun, allowing the subterranean denizens to remain appraised of celestial events on the surface. Daedal’s Sun allowed crops to be grown underground, and provided a hallowed ward against the malevolent shadows known to haunt the deep places of the world. It’s designer, Daedal, was posthumously canonized for constructing this device.
