Spiritual realm

Creatures of Two Worlds
There are two realities at play in the universe: the spiritual and the physical. They are distinct, yet related - separate, yet intertwined.

Most creatures dwell completely in one or the other. The natural animals dwell wholly in the physical realm; angels and demons in the spiritual. There are occasions when these creatures may cross from their natural home into the other - the Breach is perhaps the most extreme example of this - but it is uncommon.

Humans (including, presumably, their new humanoid cousins the elves, dwarves, orcs, and nephilim) are unique in the fact that they exist simultaneously in both realms.

For most of history, humans have only had limited perception of the spiritual realm, though their connection to it has always been undeniably strong. Since the discovery of blood metal, however, this has changed.

Some individuals, when exposed to blood metal, discovery an ability to perceive the spiritual realm almost as clearly as they perceive the physical. This vision typically comes in short bursts, and their ability to actually affect that realm is limited, but nevertheless it is a monumental shift in the way we understand the natural of the spiritual realm, and indeed human nature itself.
