The Ley Network, named so from a vekjan word meaning "life", is an invisible network of natural energies that link powerful nodes together. The fay rely on this network to sustain themselves and if isolated from it, they wither and die within days or weeks.
A witch wanting to perform her craft will need to access this energy network, usually through rituals and tools, but sometimes through sheer willpower. Fay-Blooded people have a much weaker connection to the ley network and must use tools and complex rituals to do what fay can do with a thought.
Being close to a strong "river" of ley can help a witch perform their ritual, and being on an intersection of multiple ley lines, called a node, can significantly empower the witch. Some rituals are so difficult that they are virtually impossible to perform for a non-fay witch unless they are on such a node.
