Crimson Wyrmwood [Emissive!]

Crimson Wyrmwood is as known for its beautiful crimson bioluminescent pigmentation, as it is known for its exclusivity and harsh growing climate. This root was once used medicinally by ancient high dwarven society to promote longevity. Over centuries it became harvested to the brink of extinction - collapsing the very people which came to depend upon it. Crimson Wyrmwood grows exclusively in underground rivers that flow within ancient caverns, buried far beneath esoteric ruins. After millenia the population has rebounded healthily, now sought after by dangerously expressive artisans of all types. Whoever owns even one root is likely to be extremely wealthy or adventurous. If you see someone with one, be sure to ask how they acquired it.
