Pine cone-like seed containers are rugged, oval objects found scattered around the base of a sacred tree. These tightly sealed containers can open when exposed to fire or other potent triggers. Sylvie suggested that they might serve as a means to grow new sacred trees, although the specific requirements for germination and growth are unclear.
Heyou discovered these seed containers after the party neutralized a guardian beast protecting the sacred tree. Following this, Heyou and Sylvie collected several of the seed containers, treating them as valuable resources for potential future use. The discovery of these seeds implied that the divine power represented by the trees might not be finite.
