Tiptree was a small human colony that was attacked by a small Reaper force. An asari commando unit was dispatched to evacuate it shortly after the Reaper invasion began in 2186, gathering colonists from across the continent as husks and marauder scouts were landed. Most of the team was destroyed. Several evacuation ships carrying mostly children that had been sent off world by their parents before the attack were able to flee Tiptree, arriving at salarian colonies. Tiptree was the home planet of Joker and the current residence of his father and 15-year-old sister Hilary.
