The Custodians of the Chronology is an alternate version of the Legends which was formed after John Constantine altered the timeline. In this timeline, Sara Lance was killed by a unicorn, and the three boys decided to avenge her by killing every magical fugitive they could find.
Aberrant timeline: In an alternate timeline where Sara Lance was struck down by the unicorn in Woodstock, 1969, some time after her death, Ray Palmer, Nate Heywood, Mick Rory, and Garima formed the Custodians of the Chronology to avenge Sara and to kill every magical fugitive that they could find. They killed creatures such as Konane, the minotaur, and a baby gryphon.
The Custodians went to Las Vegas, 1962 and killed a leprechaun named Red. Distraught over this, Charlie infiltrated the Waverider as Sara Lance and attempted to convince them to stop hunting magical creatures. Knowing that they've found their last target, Garima stabbed her, but Charlie instantly healed and escaped to the Time Bureau headquarters, where the team went after her. Arriving there, the Bureau and the Custodians started shooting each other. Ava Sharpe and Mona Wu helped Charlie and John Constantine escape to the jumpship. These events were erased when Charlie killed the unicorn, saving Sara's life.
