Hand of the King
Spoiler warning: Articles include story details through Episode 47 of the main campaign and all three episodes of Parental Advisory.
The Hand of the King is a criminal network recognized by Sefi, Thormir and Captain Landis, with pockets across northern Kyranda. A partial-hand embroidered patch found at Edith's house provides an investigative lead.
Landis connects its belief system with the Dragon King's return. At the forest camp, Crispin names his organization the Keepers of the Dance. Camp members carry hand tattoos. The exact organizational relationship between those names is unresolved.
The marked eastern hideout, the large gnoll camp northeast of Beckinsdale and the nearer human forest camp are separate locations, not one already-cleared headquarters.
