The Demon's Debt

Evil behind a doorway barred; three were chosen to serve as guardTaken from the surrounding wood; their souls entombed in trees they stoodWhen one shatters birch, fir, or oak; banshee’s vengeance visits mortal folkNo hero from the children of light; prevails against the blood moonlightSummon outsiders into the maze; to stand against the ancient waysCan the Warders work with former allies and enemies to defeat the banshee and prevent the rise of a new dark-elven overlord?
