Alex Mercer is not something anyone wants to see outside their nightmares. Unfortunately thanks to Louise Halkeginia is going to learn that the hard way...

Louise wanted a powerful familiar. She got it. But instead of a human boy, she got a boy roughly her age with horrifying powers over the living and a vengeful heart no one can quell. May be subject to rate change.

A killer, a monster, a terrorist. Alex Mercer was all of that. And he was tired of it. A second chance presents itself to him in the form of a half-elf, a new world and a new life. But all is not as pleasant as it seems. Halkeginia stands at the brink of disaster. From one war to the next how will this unlikely duo face the challenges to come?

A third Prototype does exists during the first Blacklight outbreak; He was relatively unknown simply due to him whisked away to another world early into the game's storyline. Halkeginia must now handle a being that is both deadly and unpredictable. Warning (Ignore these at your peril): AU Halkeginia, Slight Gary-Stu. [Under hiatus until noted otherwise - Rewriting in progress]

Infected and thrust into a new world, Collin will have to spend his second chance well and carve out a future in Halkeginia. But has he doomed them all as well?

What if Louise failed to bind a familiar to her will, especially one as dangerous as Alex Mercer the Blacklight Virus. Add in the fact that they are now irreversibly one and the same. Can Halkeginia withstand the existence of a (slightly) desperate viral creature, his 'master' and Fate's plans? Stay tune and enjoy the show. [Under Hiatus until noted otherwise]
