Node (Well of Echoes)
Nodes are fictional, naturally occurring phenomena in Ian Irvine’s The Three Worlds Cycle of novels. They often occur in places where there is a significant landmark, such as on a hill or mountain.
Nodes are places where the Secret Art can be used more successfully. They generate the field, which mancers draw upon to work their Art. Nodes also generate The Strong Forces. At first it is only speculation about the existence of The Strong Forces and the weak field is all that mancers can draw upon without being anthracised.
The Lyrinx learn to create Torgnadrs or node-drainers that drain the node of the field and render anything that draws power from it useless. Mancers who cannot draw from a distat node's field must rely on charged crystals, while clankers, constructs and any other devices of the Art will not work. There are also rare places called anti-nodes, where the Art does not work or is at least greatly reduced.
