Ogudei's Lieutenants

For the cave/undeground challenged like myself:

Go into the ruins, go down the stairs, take a left at the bottom of the stairs, go down the tunnel on the left, you'll see a square room on your minimap (that's where they are), take the first right into the next opening (looks like the handle of a cup on the minimap) proceed south until you find a break in the wall to your left, go in and hang a right and there they are.

I had some problems finding the way down to the two NPC I had to kill. Finally found them and backtracked up again and wrote down these waypoints. Put them into the addon called Paste and go.

/way Main cave enterence, 80, 17
/way Turn left. Take the stairs down. 59, 49
/way Turn right after you come down the stairs. 59, 40
/way Turn right. 57, 17
/way Turn right and follow the railroad track. 85, 15
/way Tunnel further down. Turn left 93, 48
/way 4 allience flags 79, 50
/way Opening in the wall 76, 63
/way Ogudei’s Lieutenants 68, 80

Edit: Couldn't get it to work. I messed something up, but the waypoints are right.

Just soloed these guys. Piece of advice focus your damage on Gen-li, Twister of Words.
