To start this quest you should talk to the spirit of Knight of Xantezza.
We learned that the Imp Gem was taken by the Black Ring. Without the Gem, we cannot enter the Imp Temple.

Quest stages of Running like Clockwork
1. Wargs
Kill Dagger and Snout (lvl 17).
The Black Ring Wargs won't be an issue for us any longer.
2. Used Gem
Pickup and use the Large Ruby.
We found an unusual talking gem.
3. Sent To Realm
The gem transported us into a Pocket Realm hidden inside it.
4. Time Slowed
All your characters are slowed (-50% movement speed). To remove this effect you need to reach and activate the Hyperdrive Protocol valve.
It seems that this Pocket Realm is the Imp Temple. It appears to be abandoned, and time passes more slowly inside it.
5. Imp Diary
Take Impish Handbook from the Imp corpse and read it.
Apparently we ought to deactivate the core of the Pocket Realm in the event of an emergency. The core is supposed to be very dangerous, and we should 'follow the pipes' in order to remain safe.
6. Core Info
Something happened to the core of the Imp Temple - it went out of control and killed all who were inside it.
7. Core Deactivated
Note: You only have ONE combat turn to get to the core after it spots you, before it unleashes a deathfog that immediately kills the whole party, including undeads.
The easiest way to deactivate the core is to use the pipes to get as near to the core as possible without being spotted.
We deactivated the core.
7.1. End
The core seems to be stable once more.
7.1.1. Quest Reward
8. Close Left TNI
We have ventured onwards. It seems that we will never uncover the mysteries of the Imp Temple.
