On The Effects of Astral Glory on Shadow Afflictions
In their homeland of Argus, the eredar cultivated many different kinds of plants, but so very few survived the destruction of the planet like Astral Glory has. Known for its healing and corruption-purging qualities, it makes sense that it might aid in the process of treating shadow and void maladies.
While the prayerblossom I researched likely got its curative properties from the immense life and nature energies found in the soil and surrounding regions where it grows, I hypothesise that Astral Glory was perhaps at one point blessed by the naaru, and ever since the lineage has been blessed all the same by that intense Light magic. While no doubt lessened over the years through the millennia and several generations, the gift lives on much like the Gift of the Naaru lives on in modern-day draenei, seen by the plant's power and persistance.
I have limited time in order to research these curatives, and thus I will only be focusing on how they might aid in treating shadow and void afflictions. Books on their general purpose have no doubt been written, and books regarding their care I have seen, so seek them out if these notes do not suffice.
Astral Glory has several parts that I needed to be very careful in preparing - the insect wing-like petals, the seed pod, and root clusters. I realised quickly that the stem and leaves had little use for me, and separated them to add to my compost pile. Perhaps they have a dietary function, but that is for another day to look into.
In its preparation, it was very difficult to get the seeds of the seed pods to react positively and not 'deactivate' as Astral Glory is known to do. I was not able to grind them down, though I was able to infuse water and oil with the seed essences through careful alchemical processes.
I prepared to test samples of meat steeped in shadow, rats purchased explicitly for the purpose of medical testing afflicted with minor shadow maladies, and more samples of sha-tainted soil.
Of the meat samples, tincture made from the root clusters seemed to have the most dramatic effect, though one I was somewhat afraid of. Increasing the potency of the plant that far resulted in curing the meat of its affliction, but also in the partial-cooking of the meat. The reaction was unpleasant at best, and assumedly if done on a live subject, painful.
I was hesitant to grind the very delicate petals, so I first lay the petals in layers upon the shadow-afflicted meat samples. Over time, this acted as a poultice, drawing out the shadow into the petals and releasing it safely. The petals denatured quickly afterwards, crumbling to dust. Paste made from the petals increased the rate of absorption at the detriment of using much more plant material.
The seeds did well with the rats, who seemed almost eager to consume them and drink the seed-infused water. It seemed to ease their anxiety, but consuming too much after a point seemed to increase their anxiety. I can only assume this is because of another aspect of Astral Glory I'd read about - its ability to aid others in sensing corruption. Indeed, as they consumed more, they would flee from me in the cage, corrupted with void as I am, and one even attacked me.
Consuming the seed-water and seeds whole each seemed to slowly remove the shadow corruption that afflicted the rats. Monitoring their urine content, I can only assume that it was through the renal process, but it was so trace in their urea that it might have been done in a couple ways without my noticing.
Applying the petals and seed-oil to the sha-afflicted oil had little effect, the sha tainting the soil too much for the weaker forms of the Astral Glory to overcome. However, almost anything made with the roots was able to denature the sha quickly.
Oil and paste mixed into the soil very quickly released the sha from the soil as a vapour, allowing it to vanish completely. Burying roots of the whole plant chased the sha very quickly from the soil, though it seemed to damage some of the petals of the plant in the process.
Spraying the seed-oil and even seed-water seemed to have a lesser effect, but still one that seemed quicker than the prayerblossom root that I tried before.
In conclusion;
Root tincture seemed to have the most concentrated effect, though seems damaging to use on corrupted tissues. Good for excising shadow from objects if directly applied.
Seeds when consumed seem to alleviate anxiety and reduce the buildup of shadow corruption within the body, but may cause paranoia in larger doses in individuals around corruption. Seed-infused oil and water seems to have a similar effect, though lessened.
Layering Astral Glory petals on shadow-afflicted areas serves as a weak poultice, whereas a real poultice made from the petals works incredibly well to remove shadow corruption in a quicker process from the body.
