so, when the dark elves go out slave hunting and they catch themselves some pale skinned surface elves, intended for slavery, not slaughter, how do they treat them?

now i know they hate surface elves the most, therefore worst treatment, but my wife is bugging me enough to um... make your own comparison for bugging lots.

so human slaves in Salvatores novels are blinded and deafened, usually violently. probably silenced too. other books i've read just have general hate and whatnot.

so if there is an elf slave, is it just a target of violence and weapons practice? test subject? (this product not tested on animals) what kinda long term service and a surface elf slave provide to drow?
