While the world of Golarion exists on the Material Plane, there are many other realms in other dimensions of reality known as the planes of existence. Scholars and sages call these, collectively, the Great Beyond.
The default plane for play in Pathfinder for Savage Worlds, the Material Plane operates under the same set of natural laws as our real world. The size and scope of it depends on the GM’s campaign, although the world of Golarion remains the focus of Savage Pathfinder.
These planes overlap and interact with other planes, especially the Material. Transitive Planes are accessed by powers and special abilities, allowing for travel to other planes of reality. These are the most common:
This silvery void connects the Material and Inner Planes to the Outer Planes. A traveler in the Astral Plane sees it as a vast and empty void dotted with motes of physical reality intersecting with countless overlapping planes.
The Ethereal Plane overlaps with both the Material and the Shadow Plane. A traveler experiences the Material world as if the world were an insubstantial ghost. He can move through solid objects without being seen by creatures in the natural world. Strange creatures dwell here; they can sometimes influence the real world in mysterious and terrifying ways, such as a ghost haunting a graveyard.
Best described as a warped “reflection” of the Material Plane, the Shadow Plane is a grim, colorless “duplicate” of the real world. It is infused with negative energies and serves as home for creatures such as undead shades. Plane shifters use the Shadow to cross vast distances across the Material.
The Inner Planes contain the building blocks of reality. Each Inner Plane is made up of a single type of energy or element, with inhabitants of the same type.
Air, Earth, Fire, Water — each of these elements commands its own planes, with classic elemental creatures and other strange beings such as genies and mephits.
The energies of the Positive and Negative Energy Planes infuse reality on the Material world. The former provides the spark of life, while the latter harbors the taint of undeath. In general, all characters who use powers draw energy from these planes as well.
Beyond the mortal world, these planes are the various realms of the gods and the final resting places of the dead from the Material Plane. Characters with arcane powers often contact beings from these planes for advice, guidance, and summoned allies.
These are extra-dimensional spaces that function like planes but have measurable size and limited access. Items such as a bag of holding and portable hole access these strange places.
