In Norse mythology, Valhalla is the Great Hall of Odin, the hall of slain heroes. The hall itself was massive and said to have 540 doors. Each door was wide enough that 800 warriors could walk through them, shoulder to shoulder. The huge roof was made of shields, and spears formed the mighty rafters. Only those who had shown great courage and skill in battles or adventures were ever chosen. Every morning, they went out to battle: every evening, when they returned, their wounds were tended; they drank and feasted and listened to tales of great valor. Valhalla Circuits is our great hall, a place of great skill and courage. Those who dwell here are among the chosen and have been battle tested over time.
