From publisher blurb:
A Halloween treat from Wanderer's Haven Publications!
The K'thoni are an undead race of humans from the Asunder campaign settting for 5th Edition D&D. Though they struggle to survive, their existence is uncertain as other undead hunger for the strange essence that gives them life, while the world beyond their island borders would hunt them to extinction...if their curse did not overcome the lands beyond first!
This download details the player race stats, as well as including new spells, designed by K'thoni mages, that allow them to heal their undead population. In addition, a second PDF is included explaining the break down of how racial ability scores are removed from the Asunder setting, and introducing a optional set of rules to replace them.
