Enclave J-12 is an orphanage located near Christopher's Landing, Titan. It is one of many such facilities operated by the Federation Children's Administration, charged with caring for children of deceased Starfleet officers. Timothy Sinclair was one of many orphans raised there. (Star Trek: Pendragon)
The Enclave was constructed in the 2160s. Originally designed as a short-term home for orphans of the Earth-Romulan War, eventually it became a more permanent facility for Starfleet orphans who had no other family, housing as many as two-thousand at a time. Though many of these orphans would be adopted or placed into foster care, others would remain at the Enclave until well into their teenage years. Most of those would go on to enter Starfleet Academy.
A labyrinth of more than fifty sub-levels was constructed beneath the Enclave's surface campus. These sub-levels contained medical facilities, habitat wards, research and scientific laboratories, and special projects.
Life at the EnclaveEdit
Orphans brought to live at the Enclave were separated by age, gender, and (depending on those factors), species. Older children (usually twelve and up) were generally housed in more mixed environments to encourage socialization and discourage xenophobia, while the younger ones were housed with those they would feel comfortable with and gradually introduced to the larger population as they grew up. Schooling varied in accordance with these factors as well - human children would not be put in the same classes as Vulcans, for example. (Star Trek: Pendragon: "Father to the Man")
