The Goblin DNS for ritual
Eighteen months of fieldwork in the goblin warren has produced a single reliable observation about ritual: the goblins always know which way it is, even when there is no which way.
Pattern recognition is the goblin's favorite game. Show a goblin ritual and they will immediately begin finding connections to everything else in existence. Some of these connections are real. Some are imagined. None of them matter, because the act of connecting is itself the point.

Visiting goblin dignitaries are, by protocol, never asked directly about edge. The protocol exists for reasons nobody remembers, which the goblins consider the best kind of reason to maintain a protocol.
