In 4th edition, a secret group known as the Keepers of the Forbidden Lore is devoted to Vecna. Unlike most Vecna worshippers, the Keepers reject most of the nasty and evil rituals and beliefs associated with the god; they worship him as the God of Secrets, and believe that there is some knowledge too evil for the world to know. They instead hunt down secrets and information they deem to be too dangerous for the world at large and keep it secret in the name of Vecna. This puts them in opposition to mainstream followers of Vecna who regard the Keepers as heretics, and makes them enemies of Ioun and her followers, who believe all knowledge should be available for everybody and the moral obligations on how to use it rest on the shoulders of the individuals involved.
