Blood of an angel

"Lucifer? That name rings a bell." Luna said with a pensive finger on her lips as the name sounded familiar, yet entirely alien at the same time.

"How come you don't know about him... her... whatever. It's the big bad guy! Everyone should know that!" Said Nika while crossing herself multiple times.

"Hey! It's my mother you're talking about! And don't forget that she fell while fighting for humanity and all she got in return was to be sealed, tortured and forever drained of her blood to keep her weak and to make Serum." Sam snarled.

"So that's where Serum comes from, it's actually blood of an angel." Luna said in a tone too casual to convey her excitement, her gleaming eyes locked on Sam the same way a predator looks its prey and he closed in with an hypodermic needle no one knew she even had in the first place.
