A Well-Known Secret Organisation.
In a matter of moments, the mess was cleaned up by a group of rather shady-looking individuals. But, of course, nothing about this was surprising to the Seer—he had already suspected that the entire establishment was a front. The restaurant was merely a cover for a well-known organization that specialized in information trading and contract killings: The Whistling Forest. So secretive was this organization that even its own members didn't fully understand its origins or true purpose, and they worked toward a cause shrouded in mystery.
How did the Seer know this? He didn't, not explicitly, but he was the Seer after all.
