Gaius Duffy

Gaius Duffy is a deceased human located in a cave behind the Witch of the Woods's house at Fernwood Ridge in Tiragarde Sound, along with the body of Lady Martisha and a Ritual Effigy. Interacting with the effigy will cause the two bodies to float into the air while a Twin-hearted Construct rises from where the effigy sat.

Gaius and Martisha were presumably tricked by the Witch of the Woods into taking part in a ritual that bound them to the construct.
