Villain Spotlight: Midnight Choir (D&D 5e)

What looks like a spectral delight floating eerily above the city and keening out an enchanting call is no mere phantasm or trick of the sky—it is the trap of a hunter played every night as the preamble to murder. The mutant cloaker Delonraja (CR 10) is the true source of this wonder and it remains for as long as his hunger lasts, sometimes even encouraged by wickedly unsympathetic officials keen to the unexpected coin brought in by a phenomenon common folk think is a quirk of nature. Deceptively designed by Andrew Engelbrite, illustrated by Leonardo Sa.
