From publisher blurb:
A MIGHTY BLOOD FLOWS IN YOUR VEINS
The arcane power that fuels sorcery expresses itself in countless ways: heightening the sorcerer’s charismatic influence, granting influence over the bitter winds of winter, or joining the sorcerer’s soul to the sea. The powers described herein are rare and strange, but mighty, for sorcerous blood is the essence of power. Answer the call of your birthright.
In addition, you’ll find seven new magic items for sorcerers and other spellcasters. These magic items relate to the themes of the Royal, Tidal, and Winter Kin sorcerous origins and explore their stories.
These materials were designed for use with 5th edition rules and can be played directly in your 5th edition campaign.
