Omega double center

The omega double center (ODC) is a large stadium in space that hosts many events yearly, like the sword fighting competition or the sports competition. ODC is owned by Mr. Omega Double and it is very expensive to get tickets for. Despite how expensive the tickets are, it is always filled out. If a company wants to rent out the ODC for just an hour, it would be 90,000 dollars because of how much money this stadium makes. Because there are always events happening here 24/7, many people have found out how to sneak around past the guards so that they can attend the other event for free. Because of this, Mr. Omega Double has been hiring more guards and also making sure that everybody leaves before the next event. Normally events are only 2 hours long, but there are many times when there is what's called a "day event" which lasts for 24 hours. Mr. Omega Double doesn't care how he gets his money, so any type of show is allowed in ODC, this includes fights to the death.
