Síl Croí

Sil Croi, otherwise known as the Heart Seed, was an archfey from the Feywild who kept Cedar alive following their attack by the Slaugh. He joined the Archivists and set out on the mission to find the Arms of the Betrayers along with Cedar. Eventually, after the defeat of the Skinshaper, Sil Croi absorbed the power of the creature and used it to heal the damage done by it. He passed his Archfey status and healing ability to Cedar, gave the other party members personal gifts, and allowed One to execute him to prevent the Skinshaper from ever spreading its magic again.
