I was thinking of something kind of along these lines. Maybe it should go in a different thread tho.
Basically, it seems to me like imprisonment would now be a possibility. (not slavery per se).
Why imprison? It only leaves a battery scent, not a murder scent, so it will dissapear more quickly. The person imprisoned has a couple of options:
1) Ransom their character
2) have friends or alts rescue their character
3) inherit from their character, and start a new one based on the old ones stats.
So they would not be knocked out of play, it would be more of a near-death situation where difficult choices would have to be made. Of course, imprisoning someone would still leave summonable clues, so it would not be something done lightly...
I probably am missing a large exploit hole here, who wants to point it out first? Also, I will move it to its own thread if you guys think that would be more appropriate.
