Malia gathered a considerable number of hunters with her.
Together with some of the members from different families of hunters, they joined forces for the hunters' raid.
According to the orders of their new president, each family must contribute and send their own number of hunters for such raid.
The overseer of the Vitre Family, Malia, sent a message to her foster father that she acquired a reliable source.
Which entails the location of a lair of vampires.
Hoping for a successful raid and to flaunt his good leadership, President Tony gave a go-signal and a command to all families to send their own group of hunters.
Lucas wasn't aware that his younger sister lured him out from his location so that she could initiate an attack towards the vampires.
An attack which would presumably wipe out the targets.
