The Islanders were originally the Colden Colten dogs’ "Neighborhood Watch". It was founded by Scorpio Von Rustin. As time wore on it came to include strays and cats as well.
The Islanders was founded roughly 1985, to investigate a kidnapping case. After this success, it continued to be instrumental in crime prevention under the nose of the human law enforcement. Their involvement was what turned the tide when some of the cats started dying, leading to the case being closed and the beginning of Upon the Gray Borderlines. The leadership of the Islanders is the inherited position of the Von Rustin.
The term "Islander" is also used for local pets.
