Immortal Souls (2022)

Publisher's blurb:

Immortal Souls spring from the heart of creation at the center of the multiverse. Passing through the Forge of Worlds they become echoes of themselves and ultimately inhabit heroes across known worlds empowering them to achieve even greater deeds.

Immortal Souls is a campaign supplement designed to be shared across any number of campaigns. Players add an Immortal Soul to their character and in doing so, find themselves cosmically linked to every other character who shares an echo of that same soul.

Immortal Souls start at level 1 and only advance through real world unlock events called Nexus Events. Details on how to participate or watch such events are included via links in this supplement.

Immortal Souls is both a humble campaign supplement and a large scale social project where the development and leveling of these souls takes place across real world events, played by real players.
