Into the Unknown!(RWBY X SCP) [Undergoing timeline repairs]

Wilhelm (William) Kröenen. A battle tested silver-eyed Alpha-1 Agent has had his age reversed and has been teleported to Remnant. Not knowing much about this world he sets out to learn of it, help it, and most of all to get home...
But... Will he ever go home? Will he fight in the war against the Grimm?
And does he belong here?
Note: I do not own RWBY or the Cover picture. Nor do I own Karl Ruprecht Kroenen from Hellboy. Wilhelm is merely an inspiration and in his "Canon" is the great grandson of Karl.
