From publisher blurb:
The Scion is a powerful undead cleric, once a devout servant of their god, now raised to a near-demi-god status through their unyielding devotion. They are skeletal in appearance, with glowing eyes that radiate the power of their deity. Their body is draped in the remnants of their holy vestments, and they carry their deity's symbol prominently on their chest, pulsing with divine energy. The Scion exists solely to enact their god's will, having sacrificed their personality and free will for eternal service. Whether they serve a god of light or darkness, the Scion is a force to be reckoned with, wielding divine magic with the authority of their deity.
Like the Lich is an Undead Wizard, this is an exploration of other 5e Classes into undeath and eternal life, including background and stats.
