Vampires’ Reinforcements

Right after Madeline was forced out of the warehouse by Zac's attack, the vampire sentinel used a gemstone to cast a spell, producing a white mist that summoned three of her vampire siblings to the scene.

Irina appeared first, rushing towards Madeline and asking if she was okay with a worried expression.

"I'm fine… I just need a moment to heal up," Madeline said.

"Laurent, Claudia… Be careful with those guys," she continued.

Irina turned to look at the warehouse, where they could hear the sounds of the battle between Megan and Balthazar brewing inside.

Initially, Irina believed that her big brother Balthazar would be enough to complete the job, as he was the only elder vampire of the clan.

Laurent and Claudia were the next in line, as they were a vampire lord and lady, respectively, so they were more powerful than the sentinels.
