The workers in the Fleshwerksabomination lab have already completed a number of their creations. For now, the creatures are chained to the pillars around the edge of the lab, but if we do not act, they will march with the Lich King's armies.
Grasping arms reach out of the bone piles spread throughout the Fleshwerks. These arms belong to skeletons enchanted with the power of fire. Find and free these skeletons, then take them near the completed abominations and watch the show!
Ghostwing says: Destroy our raw materials, will you? Well, the master has a special plan in mind for you...
Ghostwing snatches Olakin off the ledge and takes off with him.
Darkrider Arly says: Damn it, Olakin, get your arse back here! There's work to be done!
Darkrider Arly's completion comment is a reference to a line from the movie Apocalypse_Now: "I love the smell of napalm in the morning..." (See also here for a more complete version of the quote.)
