(OOC As agents of the Duke you would have offical seals and a letter and whatnot. I probably should have mentioned that at the beginning, sorry.)
Master Brecht listens to the groups explainations, seemingly satisfied. He then bows and says, "I see. Then I must thank you for your help in this matter, and for the Duke's attention to our plight. I wished merely to see who was disturbing Sir Lohgin's house."
Brecht straightens himself upright. "If there is anything you need of us, please let me know. I can be found either at home, or at my shop at the marketplace."
"We'll leave you now to your task. Also, Gregor's watch is over, you may wish to relieve him if you no longer need his assistance."
Providing that the group has no further questions, Brecht turns and leaves the manor.
