Seniors are an optional category of Hivers; not all individuals attain it. A senior is a Hiver who has gained special respect or status based on its actions in life. Nest leaders become seniors after several decades of service; judges of the law usually become seniors after many years in their careers; manipulators who achieve fame for their deeds are usually considered seniors. Senior status is a nebulous and unofficial classification. Within a nest (for example), the leader is usually considered a senior by nest members; outside the nest, the leader may not yet be considered a senior.
