Blooming Knight

The gardeners of Castle Tryst tend to the Stargazer flowerbed, nurturing the frail buds until they burst into bloom. Emboldened by the light of the moon, they grow rapidly and become exceptionally sturdy. Stargazer flowers are highly resilient to alchemical magic and can even ingest unorthodox substances, most notably quicksilver and blood.
Great insight into practical alchemy can be attributed to the Stargazer experiments, though controlling the weeds has proven itself daunting.
