Cassidy is somewhat short for a human, standing somewhere close to five and a half feet.  He always prefers to dress in light clothing made of common materials, never anything particulary fancy and more often then not his clothing appears to be battered and worn suggesting Cassidy has had his outfits for some time.

He almost always walks with a rapier sheathed at his left hip, though anyone who has seen him fight might notice that he seems to switch between fighting with his right or left hand seeming to posess equal skill with both.  Sometimes he'll have another small blade such as a dagger on his person and in rare circumstances he'll be seen with a second rapier, and in even rarer circumstances he'll haul around a shield though more often then not he prefers to just rely on his natural agility to avoid blows.

Cassidy speaks with a slight accent that some might describe as "lower class" something that Cassidy seems to shamelessly bear.  When the situation requries it he can be polite and when making first impressions this is how he prefers to act but once he knows someone better he'll be much more outgoing and playful.  He usually gives the impression that not a single malicious thought ever runs through his head.

Cassidy doesn't speak too much about his past but the impression he gives is that it was simply unintersting as opposed to wanting to hide some dark secrets or a troubled background. Cassidy has dark blue eyes which some might describe as intense and if you spend enough time around him you might notice that he seems to have keen senses both in noticing small details and being able to read body language.  His own body langauge will most often come off as relaxed, sometimes even cocky.

While Cassidy appears confident enough in his abilities he generally makes no show of trying to boast and insults seem to roll off of him.  When he's wearing more revealing clothing its easy to note various scars along his body, some looking more recent then others.
