Felix, an elite soldier, died in combat. He was one of the millions of people murdered every day by an unstoppable foe, who pushed mankind on the brink of extinction. His consciousness was stored in a secret bunker, but, by mistake, the transfer into a new body took five hundred years more than expected. Sadly, the only one available was of a short and weak teenager who died many years before. Many things changed in the meantime: magic, dragons, and other creatures that were once thought to be of fantasy are now common, and a new system rules on everyone and everything, allowing a person to enhance his body past human limits. He'll start again from scratch, trying to master it, but his time isn't infinite: mankind's worst enemy is yet to be defeated, and it's getting ready to finish the job once and for all.
