Setting the Signal

While some may be found creatively avoiding mobs, some cannot. Most mobs over 1300K HP and rares scattered about. If completing by yourself, best way is to run through as much as you can till they drop aggro and if you do die, die and rez close to these spots. A lot of this is timing the pats.

They do emit a static sound when you are close.

First one found at 51.67, 22.53 (easy)
Another at 56.67, 20.64 (GL getting there)
Another at 60.40, 19.65 (Not far from last one)
Another at 52.04, 19.90
Another at 59.70, 26.75
Also 63.5, 21.43

Enjoy your repair bill.

Once you complete this quest, you get a Gnomish Flying Machine (Alliance) that takes you straight to the Throne of Kil'jaeden.

Click the copter and select "Let's fly to the Throne of Kil'jaeden."

It is located next to the Flight Master in Lion's watch. (Screen shot submitted)

A little macro with the locations of the 5 Pentangulate-o-tron 2000s. Most can be placed without having to kill any mobs. Only the one at 59.7 26.8 has 2 mobs too close.
