Warlord Schnortel

This took me a while and I think I'm calling it here.
Another recent addition to my totally despicable villain league.
Warlord Schnortel, ruler of the Gomphotherium State of the fractured Ivorium Empire, a slaver empire in Zebrica feared and loathed by all the continent's denizens.
The warlord is avaricious and depraved to the extreme, taking the most beautiful slaves he finds for his harem.
He and the Ivorium States constantly make war on Zebrica, Antelopia and countless other free kingdoms, once being famously foiled in a conquest of West Zebrica by a young Zecora and Fancy Pants.
He joins Cascadius with an army of ancient rhino shock troops and his massive airship, the Ubu Roi.
His price for aiding the mercenary army is a considerable share of the plunder, an army of his own to conquer Zebrica...and Fleur de Lis.
