Who invited a cave troll to the last supper?

I'm not actually sure who the zombie-looking creature is on the left. Maybe an orc or someone from the army of the dead?

But, the rest are pretty clear. Going counterclockwise (more or less) from the top left: Cave troll, Saruman, orc?, Elrond, Eowyn, Arwen, Gimli, Gandalf, Aragorn, Frodo, Legolas, Gollum, Frodo, nazgul, balrog.
