Agents of Norse
During the seventh century, the Vikings were getting dangerously close to things they weren't meant to meddle in. The Norns discussed at length with Frigg and Freya of an unraveling. Descendants would cause an uproar. So, they held a meeting with Odin, Thor, and Baldur to resolve this future issue. They would come up with an elite group, selecting their children, their children's children, and so forth. This exclusive society of demigods would be responsible for carrying out tasks they saw fit for years to come. It was then the DNM was born.
