Everything

Each Horizon Realm – or, in Technocratic terms, Horizon Construct – must be forged with powerful magicks, fueled with Quintessence, attached to a Node, and connected to the mortal plane by pan-dimensional portals and earthly anchors, or aspects. These aspects hold clues to the connected Realm – stone walls, mystic sigils, sterile laboratories, or what-have-you – and literally keep the Horizon Realm grounded. Without these other elements, a Realm soon folds in upon itself or winds up cut off from the Earth and drifting away into deep space… a horrific fate that supposedly befell many Realms around the turn of the millennium.

There used to be dozens, perhaps hundreds, of Horizon Realms. Between the Ascension War, consensual belief, and the simple need to find safe space in an ever-growing world, mages of all kinds made Horizon Realms to fit their needs. As they discovered, though, such places are precarious. The more isolated you become – and the fewer doors you make in and out of your home – the easier it is to get cut off. And for some Horizon Realms, that’s exactly what happened.
