A Planar Keystone Setting
From the introduction:
Welcome to Hyraeatan, the City of 7 Seraphs. It’s been a long road getting here and the manifestation of many, many wills to make this place visible to you. It is our hope you will find the City as strange and alien as a new world, and yet familiar as the bars of a song you can’t quite remember all of. And if that experience moves between those poles, never quite settling on one, the job may have been done well.
The City is a magical keystone location set between an apex in the Etheric currents of the Inner Planes and the drawn breath that is the Shadow Planes flowing as a darkened river, returning reality to its source. Like a leaf spinning in an eddy, Hyraeatan spirals in a motionless movement making little headway, a gear in the clockwork of the greater multiverse. A balanced moment on the tip of a needle. There are things that can only be seen from such a vantage and wonders that can
only be wrought in such a forge.
Stories flow from the fourteen Towers of Parity. Intrigues for the would-be architects of reality and the places you will find them. And while many may come to call the portage of the Docks a safe berth or to confidently walk the edges of the Bright Lands from the luminous gloom of the Glarewood, few will ever know the whole of the gift that is Hyraeatan. But we do hope that you will try.
