You mutter darkly 'btw, dont bother waiting this npc.'
You mutter darkly 'ill go there next.'
You mutter darkly 'you might have to wait like 10 hours or so.'
Tazliel goes 'EWWWW!' in disgust.
You mutter darkly 'just come check if the npc is around here when you have
time.'
You mutter darkly 'you will find him sooner or later.'
Tazliel asks 'need him to start the quest ?'
You mutter darkly 'yes.'

Gimberto exclaims 'You will? Excellent!' 
Gimberto explains the situaion:
The DeKline Manor is inhabited by a paranoid old kobold who hates surprises.
He built a large cage maze of bars in front of his house, so that he would
have plenty of time to see people as they tried to find their way in. He also
put in a half-dozen guard dogs to patrol the maze. If he hears the dogs
barking, he immediately runs to his panic room and won't open the door until
the barking stops.
Your goal is to find the two missing packages somewhere in the maze and bring
them to the front door. Once there, put the packages on the ground so he can
see them, knock, and leave. You have to do all this without the guard dogs
ever seeing you or else the delivery will fail.
A note about the dogs: they are very well trained and will chase down
intruders. They have amazing hearing and smell, so conventional methods of
stealth won't work. Stay as far from them as you can!
Gimberto will get on top of the roof of the pub and watch the maze from above.
There, he'll start making a map based on what he can see moving inside the
Gimberto heads around to the back of the pub to climb to the roof.

cage maze. You can tell him 'map' to see what he has, but he won't respond
instantly.

What the hell was with that spawn timing? :D
