The paraelemental plane of lighting is one of rapid, dynamic change. Banks of storm clouds roil endlessly, congregating, shifting and separating to an intricate, seemingly unpredictable pattern. As the clouds go about their endless dance, they perpetually crackle with the lightning that causes the plane to exist. The unpredictable flash of lightning and ensuing crack of thunder ensure the plane of lightning is anything but a dull place. Through this unending storm float chunks of earth, literal island refuges in a storm-tossed sea. As lightning is an energy which conducts through other things, so must its plane embody both the energy and the channels through which it travels and ultimately grounds. These islands form a torus, slowly orbiting a titanic spire of dark grey rock which rises up from the seemingly bottomless gloom and is the only object on the plane to penetrate the endless storm; its summit, if it has one; sages debate whether the spire terminates on another plane entirely or perhaps is an endless loop: climb the spire long enough, and avoid getting blown off by the endless lightning strikes, and eventually you will find that torus of orbiting islands coming into view above as you penetrate the upper cloud layer.
The Lightning Spirit is dynamic. It acts swiftly, but there must always be the build-up. As the storm clouds mass and the air ionizes before the lightning strikes, so too does the spirit of Lightning build up plans and resources before unleashing them. When and where that moment may come, though, is never truly predictable.
While lightning seems capricious, striking down trees and homes, enacting change for change's sake, the effects tends toward the positive in the long run. Lightning-felled trees make way for new growth. Homesteaders build anew, wiser and more cautious. The worshiper of lightning understands that destruction is not always a negative act. It is what comes from the change that determines its nature. Thus, the plane of lightning tends toward chaos, while its denizens and worshipers decide for themselves to work for good or evil. The Lightning Spirit is not as omnipresent on the material plane as Earth or Air might be. Typically it manifests itself in a split second, sometimes as a literal bolt of lightning, other times as a stroke of inspiration. Lightning expresses itself in the material world wherever it finds an agent working to make change in a dynamic way. While other elements are often present to support their agents, Lightning trusts its followers to utilize their own strengths and abilities. It is a catalyst that ignites reactions, expecting its worshipers to supply their own motive force. There is no organized priesthood of lightning. While there are always mendicant clerics traveling the land, Lightning draws the majority of its worship from design and crafting. Wherever sparks fly from the blacksmith's anvil or an artisan's eye gleams with inspiration as her hands work their tools, Lightning draws on their creative fervor. The followers of Lightning walk may walk any path of the adventurer, so long as they practice some form of craft or dynamism. The monk, whirling and leaping to simulate the roil of lightning bolts overhead, fulfills the work of lightning as does the fighter who crafts his own weapons and the spark-eyed tinkerer who fills tablecloths and page margins with all sorts of mad designs. Lightning promotes the wisdom to receive inspiration, the intelligence to put it to use and the constitution to withstand the occasional backfire. Lightning worshipers have the following taboos: They may not impede change. Construction and destruction are both beneficial aspects of change. Wanton destruction by vandals just means there's a need to create new items of value.
Lightning worshipers do not settle down. To worship the causer of change is to remain on the move. Remaining somewhere long enough to complete a complex or large project doesn't count as settling down. Whenever possible, worshipers should revel in their sacrament. As a thunderstorm gathers overhead, they should spent at least a minute dancing sky-clad before getting their butt inside, because no one's stupid enough to be outside for the entirety of an electrical storm.
Good Omens – Lightning-struck old trees and dead brush indicate positive growth. Anvil clouds (http://en.wikipedia.org/wiki/File:Anvil_shaped_cumulus_panorama_edit_crop.jpg) suggest fortuitous times to begin designing and executing projects. The apprentice who creates a masterwork in their first attempt is marked by Lightning as someone who will do great things someday. Some artificers time their apprentice's first project with the beginning of great endeavors, thinking the quality of the apprentice's craftsmanship sets the tone for the larger work.
Neutral Omens Clear skies are the planar equivalent of "answer hazy, ask again later." The oddly bright sunshine after a thunderstorm has passed is a lucky time to begin a journey. Rainbows are even better if traveling in that direction.
Bad Omens Panicking animals foretell equal confusion and panic among the people. Degrading, collapsing and non-functional crafts indicate stagnation and lack of progress. Shelf clouds (http://en.wikipedia.org/wiki/Shelf_cloud) portend wrenching, destructive changes. New forest growth consumed by wildfire is a sign of loss and hardship; drought, famine, etc. Traveling away from a rainbow after a thunderstorm means the wayfarers will enter dark places before arriving at their destination.
