Treasure standard

During battle, blood feeds the living earth, and the trees hungrily devour the red rain. A soldier returning to the same battlefield a year later often discovers that verdant greenery cloaks the land.

Sometimes this bloody bounty proves insufficient for the land. The living earth develops a hunger for more sustenance. Greenfeeders arise from this thirst, the scent of blood, and the desire for nourishing gore. Combat draws them, and they rush in to ensure that those who bleed do so generously and often. Once they complete their horrific mission, they sink back into the reddish mud, waiting for the next unfortunate victim to venture into the forest.

They are extensions of the forest, and they have no true will or life of their own. Not every drop of spilled blood calls a greenfeeder—if the surrounding trees are healthy and well nourished, the forest has no need to supplement its diet with warm blood. Greenfeeders last about a month before falling apart, though most sink back into the forest floor long before their unnatural lives end. The healthier a forest, the less need for greenfeeders.

Summoning a Greenfeeder
Bloodshed summons greenfeeders from the forest’s floor. While in the forest, there is a base 1% chance per five points of damage inflicted in a single attack that a greenfeeder arises. Greenfeeders arise within 1d4 miles of the bloodshed.

On Porphyra
Greenfeeders are a common threat in the Holdfast of Celestial Parishes where the blood of many fey, aasimar and avoodim fell. All who travel the Celestial Parishes are cautious on the old battlegrounds for the land still yearns for blood.
