Vitaechymos
Through evolution and mass dispersion of the liquid in the form of Willows and other large species, tinier forms of vegetation have been observed to give life to smaller animals. Despite this being a relatively recent evolution, estimated to have begun a few thousand years prior, the ecosystem of Willanova's fauna has vastly diversified for both wildlife and domesticated alike.
Vitaechymos presents itself differently in fauna depending on a variety of factors, such as a species's origin, preferred environment, size, and so on. On the other hand, flora share a relatively similar anatomical structure for the substance, where a large vein of chymos runs through the main stem or trunk of a plant, and expands out in thinner veins to the tips of branches and leaves. Origin Trees, being the largest known flora on Willanova, disperse their chymo in the form of chymojewels grown on their branches; the very beginning to a new Willow!
Upon extracting vitaechymo directly from the main vein of a plant, the liquid is watered down and filled with debris, as plants will use the same veins to distribute water and nutrients. However, veins found in leaves or the end of branches contain a more concentrated and richer version, as that is where chymojewels will grow. Chymo can also be transformed into its purer variant artificially, through the collection of a large volume of the natural version and multiple strainings to remove debris and water.
Chymojewels
The default chymojewel that all life forms start out as is the infamous acorn. For Willows, that shape will change based on their personality, customizing itself to fit that individual. Companion species instead will keep the acorn variant until adoption, in which their jewel will match that of their owner. Finally, wild species of fauna will always have the acorn chymojewel.
