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.

A group of northerners want to bring the Old Gods back to the south. They grow cuttings from the white trees seeking the blessings of the Old Gods on the project, and when the saplings are big enough, they carve faces in them and secretly plant them in forests all over the south, to extend the 'reach' of the Old Gods.
The plan works of course, but the trees are *baby gods*, and behave as such when invoked.
