The SHL doesn’t really have injuries because the league operates on multiple planes of reality. It would be inconvenient to those on the higher levels if they existed, so that possibility has been simply removed. It’s kind of weird to think about it this way but it’s kind of like how the Umineko cosmology works. On the base level, the actual extant league. This is where your “pieces” are, the players and the in universe managers and all assorted lower beings reside. The players and managers are controlled by the people one layer up, your witch equivalents. (The voyagers would probably be people who do multiple sim leagues, and the affiliate passes are reflective of their higher power.) Site staff would be witches of origin/creators, everything about the lower universes (the forums for the second layer and the sim for the lowest layer) is entirely to their whims. It’s a very fatalistic way of looking at it from the perspective of a lower order being, fate being predestined and all. That’s why we don’t tell them that.
