Granite
About seven feet in height, it appears as though someone began work on carving
a statue of dark grey stone, then stopped when only the rough work was done.
While it has limbs, a torso, a head, etc, there is so separation of fingers,
for example, although it does appear to have it's thumbs separated. It's facial
features are, as the rest of it, only roughtly completed. However, there does
not seem to have any visible edges or cracks anywhere on it. It has black spots
in the area where eyes normally would be placed, they have a slightly metallic
look to them.
When moving, the joints seem to bend naturally, as though they were made of
some semi-liquid substance, rather than solid rock. In fact, when viewed up
close, it does not appear to be made of normal stone, but rather some stone
like substance that is flexible, rather than hard.
It does not appear to be carrying or wearing any clothing, gear, or adornment,
or to have any sort of decorations carved into it.
It's voice, when it speaks, sounds rather like stone sliding against stone,
which may well be exactly what is happening.
