Walt, Requiem is aka, Dr. Nathaniel Marsten. Marsten, an archaeologist, was exploring a tomb that was just excavated beneath a Scottish castle. Several new and important finds were discovered. Marsten's colleague, Dr. Jaques Levine, was overcome by greed, and wanted to claim the find for himself. So, Levine pushed Marsten into a deep pit. Thinking Marsten dead, Levine fled the the scene. And indeed, Marsten was close to death. As his life was slipping away, a strange messenger appeared to him in a vision saying that the Twilight had chosen him as it's sentinel. The messenger then touched Marsten, and his broken body was completely healed. What's more he now had the ability to control darkness. The Twilight, it turns out, is an other worldly being that seeks to bring balance to the world and defeat evil. As such, Marsten is now the living embodiment of the night striking terror in the hearts of evil doers!
