5E Race: Arboreans
Arboreans are immortal, sentient plant beings that seed human-shaped Sprouts with their memories to serve as avatars in the world. Sprouts may gather information, undertake missions, and protect their forest homes before returning to upload their experiences and consider remerging with the Tree. This fifth-edition character option includes the Arborean race, three subraces—the proud Oukken, rosy Romarins, and wild Vigne—and seven feats available to any character.
