The Open Hand is a banned network of activists in Vesk Imperial Space. It preaches that the Empire's endless mobilisation starves its rim worlds, and it spreads pamphlets and pirate broadcasts and hides deserters from the Legion. Before 120PR it had never been accused of violence.
In 120PR.0304 the Throne named it as the group behind the raid on Hollowfrost Station. The Open Hand denied it the next day.
