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.
The PCs are accosted in a major city containing at least one famous fortuneteller / prophet of the future. They are informed that their as-yet-unborn child will (insert terrible evil), and that, although they are very sorry, the PC must be executed to keep this from happening.
