Author's note.
After Dick Grayson or Robin turns eighteen he has a falling out with Bruce Wayne, or Batman and he quits being Robin and takes on the name of Nightwing.
At about this time Batgirl is shot in the spine and put in a wheelchair for the rest of her life, where she becomes Oracle, the world's greatest information broker, and as Oracle she provides Batman with the information he needs to continue his fight against crime. Her base of operations is located in the Gotham Belltower.
