From the introduction:
Welcome to the Borderlands! It’s a crazy universe here. We’ve got the murderous wild life, the murderous corporations, the murderous bandit psychos, and all the other murderous things. Honestly, this is pretty much a kill-or-be-killed setting, and you’ll probably need some flexible morals here. That, or a strong stomach, since many Bandits are literal cannibals. You can be pretty much anything you want here, just try not to end up as lunch.
