This center houses all grim championship fights. They are televised around the world. Since grim matches are now the most popular sport on Earth this stadium has had several upgrades and receives new materials and sponsorships every year. Fights take place monthly, and all are welcome to watch, though the tickets aren't cheap. The stadium itself is indoor, however because it is surrounded by a force field dome the conditions within it can be controlled to make the fights more interesting -and of course to protect the civilians while they watch. Private gyms and practice rooms are reserved for the winning fighters.
