Silent Aster Nymphilli

Introduction
Despite sharing the same name and general idea of creating a vessel to contain the soul, the Silent Aster Nymphilli are very different from the ones in White Rose. These Nymphilli have stronger souls that adapted and grew to survive the constant onslaught of attacks and things from species that also evolved because of the lack of sunlight. With stronger souls comes larger vessels but instead of expanding the vessels outwards they went upwards to specifically deal with the ever-growing trees in the forest of spirits.

History
The Nymphilli like their counterpart in White Rose is a species of noble and orderly warriors, the earliest pieces of history and literature in Silent Aster mention the Nymphilli, so one can assume they've been there since the kingdoms beginning. While not confirmed king Noct the 16th likes to believe a good portion of the Nymphilli from White Rose for some reason moved underground and started in what's now Silent Aster.

Biology
If you thought the soul of a White Rose Nymphilli was strong the Silent Aster counterpart is nothing to scoff at, the soul of this species is the strongest of them all.
