Danika was forced to shut down mouth adventurers in Curse Of Strahd when the Pack first visited her. Shakti of the Wildhunt acted openly strange in front of other patrons, cawing like a bird and trying to learn the mystery about the "friends" of the Inn. Eventually, she and her husband relented; in private, the adventurers learned the secrets of the organization. Shipments of wine had stopped from the family vineyard, and Urwin asked the Pack to investigate.
The foreigners eventually proved their virtue, and Danika became open to a party of adventurers for the first time, relaying information to them from their spy network. The Pack continued by re-securing Old Bonegrinder, providing a base of operation closer to Castle Ravenloft, which Laszlo was able to operate out of despite changing conditions in-town.
This relationship changed after the Riots Of The Blazing Sun; as one of the few selfless groups left in Vallaki, the Keepers had to mostly focus on community efforts as opposed to information gathering.
