A sinister book that forces the reader to relive painful memories by presenting idealized versions of their outcomes.
A Magic ring, made from the storm shards. It can transform the morality of a person and contain them until the world has forgotten them. In effect it renews a person after their own personal storm.
With the application of kinetic energy, this shard radiates the aura of worry, fear, and doubt that the fiercest storms bring.
Magical gem that scrys storms, and allows the wielder to “walk” them.
During a storm the PCs come upon a little boy that plays in the rain. Upon further inspection they discover that he has one eye and a long tongue lolling in its mouth. Spit dripping. It is a demon from beyond that can access our realm during storms, it eats all heads that are not its own, living and dead.
