Sandro is both a Doomscribe and a Companion of the Pallid Mask. His becoming undead offered him a great deal more free time, as such recording the deaths of local sentient beings was an excellent way to fill his time. Being a necropolitan put him in a unique position as a cleric, as well. His body becoming undead made him all the more able to hunt unliscenced creations—now immune to many of the more gruesome weapons at the disposal of the walking dead.
