The Slumbering Tsar
With a great rending and shrieking of stressed metal, the iron colossus in the pentacle-plaza begins to fall — no, not fall but lean. In fact it seems to be bending into a crouch, huge plates of black iron sheering off and tumbling to the flagstones. As the iron falls away, it reveals an emaciated and twisted body of real flesh and bone within. The massive naked body has mottled, decaying flesh, still covered in some places by clinging sections of iron plate. The lower portion of the molded iron face has broken away revealing a slacklyhanging jaw lined with sharp teeth and a containing a long, razor-edged tongue. Glowing eyes frown out of the remaining upper portion of the iron face.
Thraestos is known to be a advanced storm-giant dread ghast.
