The North Circle is the largest expansion of Sha Rephart island. Its central feature – literally and figuratively – is the Generator. This device absorbs large amounts of potential magical energy from the Voidplane and transfers it to an array of storage crystals enclosed in two rings of spheres. That energy can then be transferred into nodes within the island’s core or into vessels. There is a element of instability with this mass absorption of magic, which is why there is a large gap surrounding the Generator.

Outside of that gap is the largest park in the nation. It includes national botanical gardens as well as community gardens that citizens can apply to get a personal growing plot in. There are a trio of triangular bipyramids off to one side of the circle. These may be purely decorative.

And because it’s available, here is another shot of the entire island.
