The Other Side of Oblivion
Welcome to the Nexus!
The Nexus is an amalgam of time and space created from the detritus of broken realities. These splinters, fragments, shards or whatever you want to call them were seamlessly assembled into a cohesive mesh of all the realities from which they find themselves derived, sometimes for best, sometime for worst. Whatever the case, the worlds exist in this form, hanging in a terrible balance dependent on each other to exist, but not necessarily peacefully coexisting with one another.
Parts of the Nexus
No one really knows exactly what the Nexus looks like as a plane or planet in full detail. The Nexus behaves according to rules of its own and facilitates those rules as it sees fit. The material plane that the Nexus fabricates can change and shift as needed to fit its needs and the needs of the realities meshing together. For this reason the natives of the Nexus refer to relatively stable sections of the realities as Cores and sections that are relatively unstable or mutable as Fringes.
Cores are fairly mappable regions of similar terrain and cultures that interact with one another regularly. There are four Cores in the Nexus that are known to exist, and those four are in contact such that they form a much larger Core, but they didn’t always and many inhabitants still remember those times. Moreover, the Nexus still disrupts those bonds to test new connections (see Fringes).
The Guarded Plains, The Skyglass Basin, The Eldritch Wilds, and The Blazing Sands are the four fairly stable zones and consist of smaller lands bound to each other by conflict, alliance, common heritages, cultural similarity, or some bizarre logic of the Nexus no one really understands.
Except for one, The Tribal Veldt, which has expanded to overlap several Cores’ borders, Fringes are mappable only within a few miles, beyond that they may not remain in the same place the next day. People within the zone do not notice the change, until they prepare to leave, at which point it may be too late to recover their path by retracing their steps.
The Tribal Veldt, by expanding to overlap it’s neighbors borders, is forming connections and solidifying it’s presence. In a few years its influence may develop it into a Core also, or it may vanish as a Fringe or Core altogether, being absorbed into the neighboring Cores instead. Current map makers include it on individual core maps, but a few keep maps of it, noting the overlaps loosely with crosshatching or dotted boundaries.
