Followin' Da Blight

Listen up maggot, see dat river flowin' from da east? Wut way's east ya ask? Erm... I fink it's where da sun comes up but maybe its where da sun comes down. I dunno but dat don't matter! See dat river?! Dat's da Blight Water. Dat river is da map da Bloody Tusks gonna use to join da Waaagh! I followed it and got 'ere cuz I'z got a brain, but da udda gits in my tribe ain't got much for brains, so we gotta clear da way for dem. Follow dat river to a temple along da way. Take dat temple. Maybe we can light a fire on it so da Bloody Tusks can follow da light...

Travel up the Blight Water and try to gain control of the Mourkain Temple... presumably so a fire can be lit atop of it for the Bloody Tusks to follow. Win the Mourkain Temple scenario 10 times. Return to Bortoof Tuffjaw at Morth's Mire in the Marshes of Madness when done.
