Return to the Gnomeland Security Headquarters in the Steamfont using the Unstable Tinkered Portal at ( 1780, 453, 837 ) /waypoint 1780.14, 452.72, 837.15. Then head over to Clockwork CXXV where you will see "a stealthy clockwork". It will despawn quickly and drop a wrench on the ground ( -537, 174, 953 ) /waypoint -536.91, 174.08, 953.32. Pick up the wrench.
Head back to Gnomeland Security Headquarters in Steamfont Mountains. Target a hidden clockwork at ( -595, 175, 933 ) /waypoint -595.39, 175.34, 933 and examine the admin key to use it. You will be teleported into an instanced zone, Admin Level Access.
This zone has even-scaled ^^ mobs, called "Geargobbler System," so be careful!
Make your way east across the room (you may have to wait for mobs to path away) to the ramps to the upper level.
Invisibility and sneak will work here. Going up the southern ramp is the safest.
On the central plank (northern side) of the upper level is the Geargobbler System (an NPC) ( 6, 15, -5 ) /waypoint 5.87, 14.98, -5.39. Go through all of its dialogue options for your update.
The safest way to this platform if you don't have invis is a well-aimed jump from the large eastern platform.
Exit the instance through the door you entered from. ( 49, 1, -23 ) /waypoint 48.70, 0.62, -23.35
Return to Nell with the information you've collected.
