Boeshane Peninsula

The Boeshane Peninsula was located on Earth or one of its colony worlds, at least by the time of the 51st century.

History
In the 51st century the Time Agent later known as Jack Harkness was a child on the Boeshane Peninsula where he lived with his mother, his father and his brother Gray. (TW: Adam). He was nicknamed the "Face of Boe", as part of the publicity campaign surrounding a recruitment drive, acclaimed as the first Time Agent from the Peninsula and for his good looks. (DW: Last of the Time Lords)

The Peninsula, located on one of Earth's colony worlds (TWN: The Twilight Streets), was full of mostly grassy sand dunes and beaches. The inhabitants lived in a large building cluster at the edge. Most of the inhabitants were killed when the "most horrible creatures imaginable" invaded the Peninsula. Among the few survivors were Jack Harkness and his mother. (TW: Adam) Jack was told by his father to save his younger brother Gray, but Jack accidentally let go of his hand for a second and lost him; he regretted doing this greatly. But Gray survived this and developed an inside rage against his own brother, he eventually attempted to kill Jack, who was then part of Torchwood 3. (TW: Exit Wounds)
