I've added this to the campaign characters page, but this post includes some additional units that make up Gorfang's Waaagh as part of the
Warpstone Conflict.
Gorfang's High Command
Gorfang Rotgut: Famous (or infamous?) Orc Chieftan of Orcs of Black Crag. Gorfang is in his later years but still manages to bring together various tribes for medium-sized Waaaghs. His current Waaagh came together when he basically noticed an enterprising Night Goblin Boss named Skragg, and basically just took over.
Barrzug the Satisfied: Barrzug is a very power orc shaman that sometimes aids Gorfang. He tends to hang back on his mighty wyvern, Crakat, blasting foes from afar, content to let the annoying night goblins do the dirty work.
Skullface: Brutal Black Orc that is Gorfang's main underboss. Skullface is too out of control to lead his own tribe so instead he hangs around with Gorfang because Gorfang always finds a way to enter a good scrap. And if any of the upstart Night Goblins get a little too mouthy, Skullface just looks at them sternly. Or runs them over in his chariot.
Skullface can often be seen riding in his personal chariot, The Basher.
Oglok The 'orrible: Another famous orc boss, Oglok has joined Gorfang for this latest Waaagh. He leads a mob of Orcs called The Reds, known for the red pants, and red banner.
Oglok and The Reds
Boss Skragg: Night Goblin boss of the Crooked Moon Night Goblins, one of Gorfang's leaders. Skragg had been cobbling together a decent sized tribe called the Mad Moons within the Crooked Moon, scheming and angling for his own horde, but keeps failing. For now, the Mad Moons are a key part of Gorfang's Waaagh.
Zom the Third: Zom is Skragg's shaman. He's the third shaman because the mushrooms that Skragg keeps giving his shamans have proven to be a little too potent and they keep blowing up their heads. The failure to employ a top quality shaman has been one of biggest drawbacks to Skragg's career.
Blok the Troll: Blok is a stone troll that Skragg keeps trying to lure into battle, but every time he gets into battle he forgets why he's there.
Fred the Giant: Skragg has also convinced Fred, the local giant, to join them as part of Gorfang's Waaagh. Sometimes, Fred has a great day and gets to bash some heads, eat some elves, and stomp on some 'umies. Other days, Fred falls down.
When Fred is there with Blok, Blok usually focuses much better and generally attacks whatever Fred does.
The Slinga': Skragg swears that this contraption is going to be the thing that puts him over the top and give him his own tribe, then he can finally leave Gorfang's Waaagh and start his own. The problem is...that it keeps breaking.
The Ball Busta's: Skragg doesn't seem to realize that his pack of fanatics is really what gives him a fighting chance. But Gorfang did, and that's why he's the Warlord.
Skragg's Mad Moon Tribe: These mobs form the core of Skragg's Mad Moon Tribe. Two spearmen mobs and one archer mob.
The Flaggers: These guys are considered the "First" or "Best" mob because they won the brawl to see who got to use the actual flag as their banner. They always get the best fanatics, and end up with the best stories (whether true or not).
They're led by Bythe the Scythe, and his two henchmen Miiika (holding the flag) and Gonger (guess what he's holding...).
The Mooners: The Second Mob is the Mooners. Since they're "second mob" they get the worst, most uncontrollable fanatics, or sometimes they don't get any and they act as "bait". It's a tough life being in "second mob".
Death Stiks: The mob of archers tries hard, but they always seemed to get shot up by their enemies "better fliyn' stiks" and run away. So they came up with a new, more menacing name for themselves, the "Death Stiks" - hopefull Gork (or Mork) will give 'em some juice in the next battle.
Word on the street is that Gorfang has secured the services of an orc bolt thrower and some common gobbos, but we haven't seen them yet...
