He rides past you without a second glance over his shoulder, but you're not cool with him just running off for several reasons:
1. He's armed to the teeth under that cloak. No sane person wanders around with that many blades unless they're planning to do something. True, they're blades and not bullets but...
2. From his stance he knows what he's doing. He could do a lot of damage with those blades before someone stopped him. And...
3. He's got a weird vibe. You don't know why but you don't like him.

You've never killed anyone, heck, anything before. You hit paper targets at the end of a concrete hall along side other people hitting paper targets at the end of the same concrete hall. But you make that paper regret the day is was born, especially right in the center. The gun comes back out of your waist band as you plant your feet and take aim. The guns a semi-automatic so there's no click of you cocking but the creepy guy in the gray cloak is off his horse before you remember the safety is on. He takes a couple quick, long strides and by the time you have safety off and finger back on the trigger there's a dagger in your ribs.

"Dumbass newb," he says with a sigh as he pulls it out again.

You try to come up with a witting or insulting reply but it's hard to breath, let along think. You cough and know that it wasn't phlegm that came up. The world goes bright and cold before it all fades away.

Did you really think that would end well?
