Whoopsie, i forgot to change the topic again. We just got a sixth, waiting for him to get back so he can post his bio. However, this doesn't mean I'm not open to adding more to this after it's been started. We have someone who may add and play a second character after launch and depending on how successful it is I might turn this into a multi-faceted story arc. I've been getting alot of PMs and replies about interests and everyone's name is on the overflow list.
In short, we're at 6 now but in all likelihood that's not an arbitrary cap. Keep in touch and we can probably find a spot for you.
