Umbra and Material World

The Umbra, also called the Spirit World, the Shadow, or the Velvet Shadow, is a realm existing alongside and yet separate from the Material World

Material World/Skinlands
The material world, also known to Garou as the Gaia Realm and to wraiths as the Skinlands, is the world of everyday life with which all humans, vampires, mages, hunters, and werewolves are familiar.

Gauntlet
Separating the Earth from the Umbra is a metaphysical "membrane" known as the Gauntlet. Some humans almost manage to get close to the Gauntlet in times of bliss, meditation, or creativity; this state is known as the Periphery.

Shroud
The Shroud is the mystical barrier that separates the Underworld from the Material World/Skinlands (akin to the Gauntlet ). The Shroud makes the Shadowlands imperceptible to most living creatures and obscures Material World activity to the dead.

Shadowlands
The Shadowlands wrap and reflect the living world – every location in the Material World/Skinlands has a direct physical analogue in the Shadowlands, although the relationship can sometimes be tenuous.

Penumbra
also known as Earth’s Shadow, is the spirit world directly surrounding the physical world. Many, but not all, terrain features have reflections there

Astral Reaches
The Astral Reaches also referred to as the High Umbra, Astral Umbra or Astral Space by several mages and Ensemble Space in Tychoidian Cosmology, are the spiritual realms of abstract thought and concepts, without direct analogies in the world of flesh.

Deep Umbra,
he Deep Umbra, also called the Deep Universe, is a vast realm outside Earth's Umbral space.
