The crimson Knights where pretty much a self riteose uber guild that earnt alot of respect. Thus something like that would be player made.
My modification to the idea:
Bounty Hunter Class-
A player can use a menu to put bounty on another player\'s head. The player can specify an ammount no greater than what he/she can afford. Bounty hunters can look through this list and hunt down whichever they feel is in their league. On the defeat of a bounty head by a bounty hunter the funds are subtracted from the client\'s inventory and transferred appropriotly. If multiple people place bounty on a single person then the bounty is put into a total pot. There must be a minimum bounty that discourages random bounty, and one can not collect bounty on themselves, on players which they put up the bounty, on guild members, or on players under a sertain level. Targets with a bounty on there heads from angering another player thus become targets. This also adds a player generated quest system. Bounty may also include bartered goods.
