[@Xan the G]I would say that is before this era, but yet steam-punk seems to make that far more viable. So yes, but be careful you wouldn't be james bond. If you were to play a more realistic spy you'd cover two very good sides. A spy has to be as knowledgeable (if not more) about culture and society as a citizen of that nation. this lets them blend into the populace and act from there. Then you have your whole infiltrator side actually going into buildings retrieving documents (maybe assassinations if you want to be that guy).

you also don't interfere with robin's sort of scout ranger character as you'd be stronger in the city areas rather than the wilderness. I could see this working.

Also if you need a Q Jasper is always up for some tinkering.
