Saw the No spaceships part on the odd character class I made up 
Sorry but I hear Sci-fi I think starships an Green dancing girls lol

I was responding to your request for idea's an the class is basically a combination of a Rift's Bio wizard and the Fact I've been watching the Tenchi series once again and wondered who took care of the trees of Jurai
Hope all that wasn't referenced from too many obscure sources

I am filled with ideas that draw on but don't replicate things I've observed in anime, sci-fi and table top rpg books
Heck the potion making bartender idea reminded me of Tales of the Floating Vagabond an old RPG I read when I worked at my uncle's Gaming/comic/anime store
I almost want to see someone come up with a dwarf class that has the skill combat feasting because the idea that a character could munch on his or her foes weapons is down right amusing
