Voice of the World

Travelers via the nexus are balanced, bound, and made to conform to the rules of the world they are travelling to.
This means that the ability to use things such as magic, psychic powers, and other related actions may not necessarily be used when visiting some worlds. The characters may gain relatively equivalent abilities or aptitudes when transferring.
Likewise, characters with certain mechanical or weapon proficiencies may not necessarily keep them should those weapons if equivalent mechanisms do not exist in the destination world
TL:DR: Characters will be balanced and may gain or lose traits/abilities as they traverse between worlds of the nexus. You can't use magic if the world doesn't have it and your shiny tech won't move with you if you go to a world in ye olde days. You'll get relatively equivalent equipment and/or stats.

Manifestation

Its a voice that echos in your head as you move from one world in the nexus to another. The voice varies by world and tells you an approximation of the changes you can expect.

Localization

This applies to when traversing from one world or nexus node to another, the exceptions being Nexus Node - "The Arena" and The Atelier.
