The arena is just a place for crazy people to fight each other. Practice writing epic fight scenes here.
What is the Arena?
The Arena is a place for writers to practice writing epic battles.
What kind of epic battles?
Any kind! A physical struggle. An arguement maybe. Anything that your heart desires.
Sometimes I just feel like writing short little skirmishes between two samurais or something. I'm sure other authors feel like that sometimes as well. At any rate, this is just a place to practice writing fight scenes.
What if I feel uninspired?
Write up a character and have him fight against a character who has already battled in the Arena previously.
Nope that's about it. No need to ask if you can jump in. Just...do!
