Lay Lines

Lay Lines are strong lines of magical and spiritual power. They exist within Spirit Realm, Mortal Realm, Shadow Realm, and Fairy Realm. They are the source of most magic. Studied by magic and spiritual casters alike.
Lay lines may be altered or changed by spirits or magic. When magic users alter these lines if they do not know what they are doing can cause cataclysmic events.
Where these lines meet are called nodes. In places where many lines meet these nodes are called nexuses. Nexuses cause rare herbs and minerals to form. Magic users might seek out these Nexuses to increase their magical power. Equipment and items will become magical if they spend enough time in these Nexuses. Raw magic is emitted from the nodes. The raw magic flows throughout the world, touching every corner of the planet, with the exception of dead-magic zones. If a caster seeks a node they can increase the effectiveness of their spells exponentially while in the vortexes.
There are corrupted nodes that cause many strange effects on those around them. Most form due to inexperienced casters trying to alter the lines. It is speculated that shadow magic emanates from these nodes. Casting a spell concentrates the energy emitted by the nodes to create an effect.

Manifestation

Lay lines are only visible to those that can see into the spirit realm. The lines appear as cracking purple electricity flowing in a strait line to the nodes.
At the center of the node are vortexes of wind and electricity. The vortexes can stretch for miles into the sky. Corrupted nodes appear as will appear as a large black heavily obscured mist.

Localization

Many of these lines form around structures, ruin, city's, and sources of concentrated magic and spirits. There are anomalies on the planet such as dead magic zones, wild magic zones, or corrupted nodes. Places where the nodes or lay lines have been damaged or are non-existent. Zones of wild magic exist were a node is not connected to a lay line. Dead magic zones are places where the energy emitted by the nodes has been exhausted.
