Archipelago of Ages

A man named Raven dies tragically in a sudden catastrophe within a crowded building. He awakens reborn, in his physical prime, standing on the exact same spot but centuries in the past, surrounded by wild nature. Granted a mysterious, unfeeling System, he must navigate this ancient world, relying on his reclaimed abilities and the System's power to survive, unravel its purpose, and forge a new path out of time.
