The custom of storm-peace evolved long ago in response to the sudden and severe storms that plague the Shimmering Isle. Over the years, with Noblesse influence, the practice has become ill-used or forgotten, specifically with the Noblesse. Many of that race scoff at such a “savage” and “non-sensible” notion. All characters who hail from Cael and Waelund, and most Seitsmen are already be aware of it.
The basic concept is that an automatic truce exists between all individuals and groups who seek shelter in neutral territory during a lightning storm. Such weather is simply too dangerous for fighting, regardless of people’s feelings toward one other. Storm-peace is assumed to be in effect unless someone specifically rejects it. Even so, whenever two strangers meet during a lightning storm, they often greet one another by asking “Storm-peace?” simply to ensure that the other knows and respects the tradition.
Storm-peace applies to any thinking humanoid, though not necessarily to other creatures. Many people assume, however, that it applies to any creature able to ask for it, and many legends tell of bards singing songs to dragons or other dangerous monsters during a storm-peace. Any character who makes a successful DC 15 Knowledge (arcana) check knows and can repeat at least one or two such legends.
