Planesmith
From UnderlightWiki
A dreamer able to shape energies and fashion them into constructions. Their skills range from the ability to install new item generators, redirect portals, change rooms, to build entirely new planes.
Each Planesmith uses different methods. Planesmithing is a skill achievable only by the most powerful and proficient Dreamers.
Famous Planesmiths include Aethimir, Gloktr, and Kanto.
Planesmiths are distinct from Dreamwrights, the original crafters of the Dream itself. Their identities are unknown. Their ability far surpasses any current Planesmiths, who can add to or change our City, but are not able to create an entirely new instance of the Dream.
