You all manage to shed yourselves of metal by the time it enters.
When Manjab enters, you instinctively take a step back. The thing is an aberration, perhaps a golem or living statue or something meshed into a hybrid of nightmares.
Standing about 12 feet tall, its body is formed as if from various metals--steel, iron, bronze. The upper torso and shoulders are covered with ancient script and runes that glow lightly and eerily blue. Its upper body is humanoid in appearance, with a smooth, bald head. Its two arms diverge from humanity. The left appears to be a large set of shears or pincers as long as broadswords and as wide as a man's girth. The right arm ends in a dangling 8 foot chain with a flanged and hooked head like a morning star but large as a small anchor. Its hooked flanges are barbed like those on a fishing hook. Its legs and lower torso consist of lengthwise blades -- as though dagger and sword blades radiate around its legs, knees and trunk.
Its two eyes glow. One eye is an azure jewel, and the other is a dark onyx gem like the one Shae grabbed from the mouth of the dragon pedestal before you were all sent to this labyrinth. But unlike the one Shae took, this one glows with a deep blue from some unknown source.
The other strange thing about this creature is that a sickening green mist or smoke continually emanates from its joints and the spaces between its blades. The mist rolls from its mouth and neck joints, and from its ears and every pore. It covers the thing with a fine billowing layer.
It sees you and immediately begins to approach.
