- For the similarly-named character, see Astra.
After Astra was possessed by a demon, John Constantine, Anne Marie Flynn, Gary Lester, Ritchie Simpson, and Chas Chandler all came to her aid in a attempt to expell the demon from her body. John attempted to summon a greater demon, Nergal, to instruct it to expel the lesser demon. While the plan worked, the demon also killed Astra violently in front of everyone and damned her to Hell for Eternity.
This violent act lead to the group of magic users to split up, and John to place himself in Ravenscar Psychiatric Facility for the Mentally Deranged, where he continued to be haunted by his actions. Anne Marie became a nun in New Mexico, Gary started to do drugs more often, and Ritchie put it behind him.
Eventually, John was offered the opportunity to stop the "Rising Darkness", and chose to do it to honor Astra.
While possessing Sara Lance, the demon Mallus used Astra's voice to offer Constantine Astra's soul in exchange for Sara's. John did not believe him, and continued to exorcise him. John later told Sara that had he believed that Mallus was telling the truth about freeing Astra's soul, he would have taken the offer without any hesitation.
