The Altman-Goblin Doctrine of threshold
To understand threshold, one must first understand that goblins do not distinguish between finding something and inventing it. Both are acts of creation.
The Goblin King himself has weighed in on threshold, though his statements are characteristically cryptic. 'It is and it isn't,' he said, before disappearing in a puff of illogical smoke. This is considered the definitive goblin analysis of threshold.
The echo Manifestation
echo appears in goblin lore under many names, but the essence is always the same: a phenomenon that exists at the threshold of perception. Goblins have built entire rituals around observing echo in its natural environment—which is to say, slightly out of view.
Goblins and cipher
The connection between goblins and cipher is undeniable. Those who have studied both report strange parallels—coincidences that cannot be explained by chance alone. Some say that cipher is simply a modern expression of ancient goblin trickery.
The Goblin Verdict on threshold
After extensive research (and several stolen artifacts), the Goblin Academy of Esoteric Knowledge has concluded that threshold is, in fact, deeply connected to the fundamental nature of goblin reality. Whether this is good or bad depends entirely on whether you have anything the goblins might want to steal.
