Although skarring is not the citadel's official sport, it is quite popular. It is quite common to see groups of teenagers playing the game in skate parks. There is even a large group that makes "official" outfits specifically designed for skarring, as you can see in the picture above.
The name comes from a combination of "skating" and "sparring", as it involves combat on roller skates.
As for the sport itself, it's rather simple.
Two teams find a skate park, and scatter non lethal weapons around it.
Most commonly you'll see two pads on each end of a handle, which make a good blunt weapon. Or you'll see a basketball. Nothing special, just a regular basketball. It's mainly used to knock opponents off balance at longer range
The only rules when it comes to weapons are that you can only carry one at a time, and that you can only attack other players using said weapons.
There are also many general safety rules which don't need much explanation.
The way you win is by eliminating every opponent, this is done by knocking them to the ground three times. After that, they're out.
As long as these rules are not broken, it's a free for all.
