Hahaha, don't be thrown by the Halo font. John-117 is not the "military captain" I was thinking of, I just thought it was suiting. But he will probably be joining the ranks alongside Grimmjow and the others who want to squish the dog pack like a bug. He's not quite evil, just...grumpy...
As for the plot, well...a commander is rebuilding a tight-knit army of mercenaries in the Lone Lands, partially to regain the prowess he once had, partially to taste blood and victory again. All are welcome to try and join, but there will be brutal struggle if one is to be officially admitted. Not all will survive. But once in, you are forever bound to the clan and its benefits. Other associations would become secondary, for you will be apart of perhaps the most elite league of killers anyone has ever seen.
A vague explaination there (I don't want to spoil anything), but I have a draft for the first post. I just need to, uh, wait for the right time and the green light to go.
