Location Interference is the name given to a hidden Northworld mechanism for obtaining specific skills to create one’s build.

The easiest version is the Geomantic, or leyline interference. Each leyline type, the intersection of identical leylines, and the set of all 4 leyline types have 3 specific Geomantic skills associated. People acquiring a skill from the lottery at a place of leyline interference get one of those three at random. Each skill can be obtained by other means, the leyline interference is merely a mechanic that guarantees one of the three unless you already have all of them. Each leyline combination can be used only once for skill acquisition, no matter the location.

Unsuspected by most, it has fueled the legend of the Stones of Tarquar (where 3 Minor Leylines intersect) as people think they can practice magic there and then gain powers through the lottery. The only people in Y6 who had a better clue were the Earthen Brethren, whose Keep stand at a massive leyline convergence (3 world leylines, 2 major leylines, 1 standard leyline, and 2 minor leylines) and, of course, have noticed the fact that standing in their ornamented courtyard plaza let them pick a number of guaranteed geomantic skills. But their theory was that it was a specific device installed in the Keep’s courtyard, not a general mechanic.

It was not until Archmage Vantegaard obtained a Sense the Leyline skill and was able to observe directly the mechanic in effect – and choose which of the available skills he wanted – that the Geomancy puzzle was solved.

Once that happened, the Aetheric interferences linked to specific magical leyline-powered structures and Druidic tree-ring interferences were quickly discovered.

It is suspected that a similar mechanic may apply, not only on magical abilities but on non-magical ones and even affect a Gater’s initial Setup.
