Missed the TOR cut off with this one, but Gorgol’s artwork doesn’t match with the description in TftLL — there it says “These Orcs are led by an Orc-chieftain named Gorgol, who wields a mighty axe taken from the tombs of the Dwarf-kings in Gundabad.”
However, the artwork in the Moria book has him wielding a large sword instead.
