Sing a Song of Blackbirds
Thornlings are strange plant-beasts, roughly the size of a large dog and composed of dead wood and long brown thorns. They have six insect-like legs and glowing green eyes. Those attacking the thornlings must beware of the spikes that cover its body, and those that successfully strike the thornlings are always affected by the thornling’s magical aura of vengeance. Little is known about the thornlings, and they have only recently become a threat to civilized areas as various locations along the Mahogany Coast become corrupted by an unknown power. It is hypothesized that they are the physical manifestation of an area’s anger at the meddling of mankind.
Removing the corruption from an area apparently neutralizes any thornlings in the area, as observed in the case of Willowmaid where after a brave band of adventurers successfully drove off the corruption that was plaguing [[Willowmaid Marsh.
