Leylines and Foci

12.1 Leylines and Foci

A leyline is a single thread in the tapestry of the ley, a complex web of lines of power deep beneath the earth of Sapience and indeed all of Aetolia. This network is formed from the interactions of the planes; major leylines are formed by the intersection of large, stable bodies, while the smaller, shifting leylines are formed from the interactions of more unstable planes. 

When these lines of power become saturated with ylem, they release their excess in bursts of power called foci (singular: focus) which are then able to be harvested by those with the requisite training. 

Cities will often fight over these foci, extracting their ylem through use of the Refining skillset.

There are currently three known types of foci: Major, Lesser and Minor.
