We tried, Etrigan. We tried and failed. How long did we flounder with the absurdity and whimsy of magic? That has all been brought to order under Merlin. He has accomplished all that the Justice League Dark could not. For once I was offered a choice to be on the right side. So...will you yield? 
- — Jason Blood src
Jason Blood is the Blood Knight, a warrior in service to Merlin.
History
During the Magistrate's takeover of Gotham City, Jason was held captive in one of their detention facilities due to his alliance with "masks". He found himself as part of Spoiler's gang, and he eventually helped with the insurrection and breakout of the prisoners.[1][2]
Years later, as Merlin began trying to bring the forces of magic under Earth's control, one of his first tasks was to separate Jason from the demon inside him, Etrigan. When they were apart, Merlin let the world believe Blood was dead, while instead he recruited him to his army. Jason became Merlin's Blood Knight, and joined him in his war on the supernatural, even against his own former allies in the Justice League Dark.[3][4]
