For the Horde!
Word of the failure of Operation: Gnomeregan and the
ensuing siege has reached the pointy green ears of the always
opportunistic goblins. With all the chaos, it is a perfect time to
steal technology out from under the noses of the gnomes.
While generally inferior to goblin engineering, the gnomish
inventions can often be used to springboard into grander and
more destructive machines. The adventurers have been hired
as a sort of mercenary strike force to support the G-Team, an
infamous group of goblin commandos, in the pilfering of the
fallen capital. The party should report to Chief Engineer
Scooty at Grom'gol in Northern Stranglethorn. He will send
them to the Entry Tunnel in the Hall of Gears via a goblin-
engineered teleporter, the Transpolyporter 9000. Sprok, a red-
shirted goblin engineer, mans the other end of the
Transpolyporter 9000 within Gnomeregan.
The party still gets all "The G-Team" quests, but the G-Team
is now goblins working for the Bilgewater Cartel instead of
gnomes. The gnomes of the Clean Zone are naturally hostile
to the adventurers. Tink Sprocketwhistle, the leader of the
holdout gnomes within the Clean Zone, is in possession of a
Mecha-Bond Imprint Matrix.
To leave Gnomeregan, the adventures must return to Sprok
and the Transpolyporter 9000 in the Hall of Gears. Upon
successfully returning from their mission, the party will be
handsomely rewarded by the Bilgewater Cartel for their new
"acquisitions".
