I am thinking maybe a dwarf. They would probably be a good solo race, as they get second wind as a minor action and are harder to push around. In terms of the setting, I guess they would be a dedicated foe of the spider elves, though perhaps they are adventuring above ground in search of something. Either power, glory or aid for their cause.
What level were you thinking of starting at? 1?
Hmmm... Dwarf Ranger 1
