"Well, that's a story and a half." Knife started, "It all started when I came across another nexis world like this. I was in Los Angeles when I was carjacked by two author avatars. For some reason we time traveled to the future after a some apocalypse. On a roadtrip across the US we were attacked by a flock of giant mutant birds, and Doug here." Knife paused and waved at the bird, "He bit off my hand."
"Yea, it was pretty mad.
"Right, so following the righteous beatdown I gave to the flock, Doug decided he didn't want to become a thanksgiving dinner and stuck with us. After that we met up with these crazy technophiles, like, 'last bastion of the government, going to save the world from the dirty muties' kinda thing. I lost my leg to a point blank .50 cal shot," He place a hand on his left leg, "Trying to break one of the author avatars out of captivity, and for some reason they recruted me, gave me some fancy robotic limbs and put me to work."
"Of course I stole their experimental time travel device and went back as far as we could, only to find ourselves in the ruins of Rome. So, nothing else left to do we jumped to another universe and we've been traveling together ever since."
