Ley Lines

Ethereal Ley Lines are ribbons of ethereal flux that encircle the world in circumferences that intersect at ethereal source points (ethereal poles). Access to ethereal power is greatest along these lines.
Ethereal Nodes: These are the spots on the planet where the intersecting primary and secondary ley lines form a worldwide ethereal grid. Nodes are often classified according to their proximity to the primary ethereal poles, and the strength of the ley lines.
Ethereal Poles: Similar to magnetic poles, ethereal poles exist on opposite sides of the planet (not equivalent with the rotational poles). There are two pairs of poles, the primary and secondary poles, from which extend spoke-like ley lines that meet together on the exact opposite side of the world.
In functional terms, the ley lines are where those trained in Etherea are best able to draw upon natural energy. In the course of history, many monuments, cities, and holy sites can be found along these lines. For example, the Temples of the Sky were built on even earlier sites, that fell along the primary ley lines. In addition, when the ancient Fae and Düergun craftsmen worked to build the great ethereal Gates, they allowed long distance travel to take place along the path of the ley lines.
