I've recently introduced my friend to D&D and started a new adventure. There's only two players, so I'm playing a NPC as a PC. The new player is really fond of Assassin's Creed and her character is a former assassin, so I made the NPC a copy of Arty (for my own enjoyment as well, of course). I'm using generic stats for him at the moment and haven't roleplayed much, so I'd welcome some advice and making a full character sheet and roleplaying.
I'm sticking with the LE alignment and using Pathfinder rules.
