Although EC's horror stable consisted of three separate magazines, there was little beyond their titles to distinguish them. Each magazine had its titular host, but the hosting duties for any one issue were typically shared with the hosts of the other two. Thus, a single issue of "The Vault of Horror" would contain two stories told by the Vault-Keeper, one by the Crypt-Keeper (of "Tales from the Crypt") and one by the Old Witch (of "The Haunt of Fear"). The professional rivalry between these three GhoulLunatics was often played for comic effect.
