A woman with a body count in the thousands. Don't mess with her.
Rosa is cold hearted and revels in the thought of grieving wives and families of the men she slaughters. She only has this attitude, however, towards her enemies and assassination targets. Otherwise, she's outspoken and a bit of an attention seeker. She is deathly afraid of spiders, but not other creepy crawlies. She isn't very good at keeping a low profile for very long, so she needs to work quickly in order to get away with getting rid of her targets. She is very intelligent and plans each kill meticulously, very calculating in other words. Her Assassin allegiance, and swearing to the Creed have made her proud of who she is.
Assassin's robes, Hidden Blades (one on each hand), long sword and matching short sword, arrows and a bow, a satchel (for keeping food scraps and other assorted stuff, a water skin (or a canteen made of animal skin).
Her equipment is often hidden by her robes but very accessible to her in case of urgent need. She usually has something like fruit or some meat in the satchel. Her bow is somewhat short, but is perfect for her body configuration. The arrows are short as well and aerodynamic so no wind resistance can mess up the trajectory or the impact. The water skin is made of a tough version of buckskin, double reinforced to ensure no leakage.
Rosa was sworn into the Assassin brotherhood (not exactly sure what to call it) at a very early age due to her adeptness at survival and her parents also being Assassins. Her parents taught her to kill and be wary of others. They also taught her to try to not get attached to anyone that isn't an Assassin, otherwise she'd be in for heartbreak if it comes to the point where she'd have to assassinate the person she's friends with if they bat for the wrong team.
