The High Meadow was once a symphony of eternal spring, and Keryx was its finest conductor. As a piper of the Summer Court, his music could coax the very blossoms to open ahead of schedule. But on the night the Blight-Walkers arrived, Keryx was lost in a stupor of distilled elderberry nectar and fey-dust. He woke to a silent grove of ash and weeping rot, his silver pipes melted into a useless slag. The silence of the dead trees became a screaming accusation that has never stopped ringing in his ears.
Desperate for a way to fight the decay he had ignored, Keryx sought the forbidden alchemy of the Order of the Mutant. He learned to distill the remaining magic in his own satyr blood into a corrosive fuel. He didn't just join the Order; he redesigned his own anatomy to be a weapon against the parasites of the Feywild. He now moves through the world as a traveling reveler, but his merriment is a trap for the dark things that hide in the corners of parties, feeding on the excess and joy of others.
Keryx exists in a state of chemical warfare with himself. He maintains his boisterous persona with the same precision a clockmaker uses on a gear, hiding the fact that his veins are filled with toxins that would kill a mortal. He carries no pipes now; he says his music was 'too quiet' for the work that needs doing. Instead, he drinks from a horn-chalice that never touches wine, only the mutagenic sludge that allows him to see the monsters in the dark.
