After I made my current guard character back last year I fiddled around with the idea of a character that was a lawyer or merchant type character. I wanted to play them Chaotic-good and had them peddle goods they either 'found' or got from story webs or such. Probably would have been an Altalar or half varran.
One character that I actually made and had a good time with was my first Sihai. Their name was Yura and I had a magic perm at the time. It was right before the reset so you still had the old system with the old magic schools. Their background was that they where a military type that helped build ships and work metal. Magic I had with them was Ghost Control, Ghost Blades and so on. I only got to play her for a week with magic before it was reset. Though I had a lot of fun experiences with her.
Some ideas I had but never really fleshed out like the other ones was a Daen Whaler and a Alior gambler.
I probably have a lot more but the main one that was the first idea I had was a Halfling Rouge. Since there's no actual halfling race I'd probably have to use an alior character and just say they where rather short to do it. He'd be Ithanian and use a rapier as his weapon. My build for them was gonna be stealth and rouge-like really. Probably would have him do crime or mercenary work. The new system makes it almost perfect for what I had in mind.
Bit of art I did of what I had him pictured out to be. Nothing to old but late twenties or mid thirties. He'd be 126cm or four feet tall. Just short of a broom.
