Bagog the Elf-Eater, was an Orc Warchief with a wicked axe and some really bad habits: beheading prisoners, eating elves, drinking blood, you know Orc stuff.
His "blood mead" got poisoned by the party and they managed to sneak it and take his head.
He has three lieutenants: an orag, an orc eye of gruumsh, and an ogrillion. His army was quite large and he was able to rope in 7 hill giants.
