The castle, originally called the Halls of Zuberi, was constructed around the turn of the 44th century AR by Meskhenet, a mistress of a wealthy Osirian merchant named Khalfani Zuberi. She abandoned it in less than a decade, upsetting Zuberi into abandoning it completely. The castle collapsed years later.
While most inhabitants of Cheliax consider the ruins simply an abandoned mess full of greasy, corrupted plants and fungi, it is in fact secretly inhabited by blighted fey led by a blighted huldra named Lenira Re. The fey seek to corrupt the Barrowood, and capture fey and humanoids who pass by the ruins in their pursuit of this goal.
