I'm actually looking to form an organization of sell-swords. Mercenary adventurers who will hire out their services for various quests, and when the game progresses to that point, possibly even for various wars.
The goal would be to build a community who have agreed on certain 'prices' for their services, and who are available in major locations to 'assist' in quests for those prices.
The contract would be fairly simple:
The customer must pay contract fees half in advance. In case of failure to achieve the goals of the mission, this deposit is non-refundable.
Customers who do not pay the balance on a successful mission are blacklisted for life, unless they pay ten times the balance to the guild.
Customers have first choice from the spoils, but the contractor receives their fair cut as part of the contract.
If a contractor fails to fulfill their contract, the guild will make every effort to fulfill it, and the contractor will be subject to sanctions appropriate to the situation.
Thirty percent of the contract fee is due the guild, to finance advancements for the whole. Spoils of battle and the remainder of the fee are property of the contractor.
------------
I think that, given the sandbox nature of the game, such a guild could have great potential to really make a mark on the game. And if down the road when such things are available, a castle or city were to need a powerful guild to keep it safe. Well then, I'm certain they would be available.
There would also be need in such a group for able crafters and cunning merchants, to help gear the mercenaries and sell the spoils of adventuring.
Hopefully I can find other people that would be interested in it.
