After the war, newcomers such as Magna and Dante are introduced into the series. Oceanside, another community out at sea, is established, as well as safety perimeters across the DC area, which are violated by the presence of the Whisperers, a tribe of people disguised as the dead who have rejected the notion of re-establishing civilization. The leader, Alpha, antagonizes Rick as her daughter, Lydia, forms a romantic relationship with Carl. When Alpha's second in command, Beta, takes leadership of the group, he declares war against the communities.
