Portals

Portals will for many be the main way to get around on the grid, that is, between worlds. The portals hold the important task of connecting worlds, and transforming elements about the travelers so they may fit worlds better. This usually is a basic change in clothing, or changing Munny into Dollars in Manhattan, or even sometimes a transformation of one's form to reflect a world better - such as in Halloween Town. However, they will never give abilities you did not have before, or take any away for that matter. The only exception is a world where it is 'required' to do so for one's survival. Like being turned into a sea-creature for Atlantica world. However, none such applicable worlds exist on the grid at this time.

Permanent Grid Portals

Malificent has connected many a world through the power of her magic. To do this, she used the powerful dark sorcery known as Dark Corridors. These are Dark Corridors create a trans-dimensional pathway that uses the force of Darkness to connect two points immediately; and this is also the reason that Heartless get attracted to these worlds. However, these portals in question do not get moved, and cannot be closed.

Portals of Darkness

Shadow Lords, and a rare few with hearts dark enough to wrest control over this very element, have gained the ability to open and close these portals anywhere at any time. Though they are no combat technique, they are often a way to arrive or leave locations whenever the individual desires it so. It's rare to be able to follow such people through their own portals. They can however not open them to places they've never been to!

Corridors of Darkness

The corridors of darkness themselves are very much like hallways. A single plane one can walk across to the other side. It's not rare to find Heartless hiding within these, but they are rarely the strong kind. These corridors are also rumored to darken one's heart as one uses them - but the Permanent Grid Portals do not have this effect on those who pass through them.
