Christopher is the bandit who guards the entrance to the Bandit Camp. He will only let you in if you already know the password, 'Beetroot'. Hopefully you got this previously from the bandit Martis, when you helped him escape from his cell during the quest In the Bandit's Den.
You can mindread Christopher twice for different results:
- Mindread him before he admits you to the camp and you will gain one stat point.
- Mindread him again after he lets you into the camp and you will learn he wants some Rimmer's Rum, which can be found further into the camp.
The Rimmer's Rum will allow you to to succeed with a quest called Couple Trouble, in which you help Clement and Sybile escape the camp to start their new life together. How sweet.
