Is HSAR the most awesome guy in Europe?
Well, let me tell you a story about HSAR.
Once upon a time, HSAR rocked the Reclaimerverse with his intense and immensely detailed stories about the Cavalcade entities at the height of their power in Forerunner society. Great ships traversed the galaxy at their direction, messages sent via the great communication networks, and so on. The great and mighty HSAR was a significant contributor to the Reclaimerverse mythos.
And then HSAR disappeared. His contributions to the community still stand as a monument to his greatness, but the man himself has not been seen in an age. We can only hope that he will return again one day.
