Here's a simple forum game: Take some element from WoW and add a plot twist to it. The more twisted, the better!
I'll start: Fish Fellreed is actually a Jinyu warlock in disguise named Fish Felheed! The pigs she gave you are actually Felhunters, and eventually, they ate Farmer Yoon and destroyed his farm. Than they did the same to the rest of Halfhill. Afterwards, she took over Pandaria and Built a Demonic Fortress in the Heartland. Her Fortress becomes a Demon-Jinyu themed 12-bosses Raid with Fish as the last boss!
