Sphere of emanation

Spheres of emanation were the range at which it was possible to channel power from a deity. In the I.C.E. Age history, the concept of "local gods" was more prevalent, who had much more limited scope. Their power would be tied to a physical location or "holy site", and they would become weaker as they moved further away. In principle this was true of all "gods", even the Lords of Liabo, who would not be able to survive outside of the solar system. However, when such a local god was at the focus of their power, they would become very formidable. It would be very embarrassing to lose such a fight, so the Liaboans usually allowed local deities to rule their own domains with autonomy. In the Shadow World history, this was a major factor in their distant relationship with the world, because coming down and directly interfering would upset ancient balances of power. The Lornon gods were unable to do so because the Liabo pantheon was more powerful.

Holy sites were much like Essence focii, or "nodes", except that they were sentient with "pseudo-personalities." Thus, they would express ire at being tapped by those they found disagreeable, which was more or less the basis of Clerics. The sphere of a minor god might only be one mile, whereas others spanned the whole planet and beyond. That means if your power derived from a local god, and you were beyond their range, you would effectively be unable to cast spells based on channeling that power. Local gods would also be much more likely to notice inappropriate use of their power. They would be more likely to directly aid a follower, but said follower would be more vulnerable elsewhere.

The Graveyard might be a sphere of emanation, with Bandur Etrevion being an extremely powerful channel of Unlife. This would explain why the Ice Room is a node, and why the forest never grew back after thousands of years. There was a modern example of the concept in Meyno's Shrine, which used messaging that implied it was a "greater essence focus", an archaic type of node. These effects were removed after Meyno was released, at which point the room was no longer a node. When a god was "dead" or "killed" in Shadow World, it meant that they were rendered unconscious. In other words, they were "permanently discorporate", possibly lingering as a node but with no conscious will.
