Mission name: Cleaning the Rust.
Mission rank: C. [Quest] [Non-Repeatable]
Objective: Convince current ownership to sign away the remains of Iron Falls....as delicately as possible.
Location: Kirigakure - City.
Reward: 300 Ryo + 1 EP.
Mission Description: A mercenary corporation isn't the easiest thing for the public to simply forget about. In certain circles, rumors of its existence float around, but upon even a cursory investigation, the premises are all but deserted. After finding the benefactor to the organization, it's time to get things running under new management.
Development References: Iron Falls. The wealthy benefactor to the organization had their information revealed in this thread.
Mission Details: This mission requires an extra 500 words to complete. The only thing you need to do to succeed is to convince the wealthy ex-shinobi benefactor to sign over rights to the Kiri chapter house to you. He was a powerful Ninjutsu, Taijutsu and Bukijutsu user, so violence is not a wise choice. Presenting your plans for the organization might be a valid goal, or perhaps simply focusing on the failures of the current leadership would give you a chance at reform. Given the severity of the latter, failing this mission mostly entails threatening or attacking the benefactor.

Mission name: Iron's Fall.
Mission rank: C - Special Repeatable. [Quest]
Objective: Wrest the skeleton of Iron Falls from any remaining members.
Location: Konoha - Dense Forest || Iwa - Gisei Lake.
Reward: 300 Ryo + 1 EP.
Mission Description: After having the organization technically handed over to you, all that's left is to either oust the current membership or turn them over to your leadership.
Development References: Iron Falls. "Cleaning the Rust" must be completed to take this mission.
Mission Details: Unlike most Quest Missions, this mission can be completed three times by the same person so long as it is performed separately in the three listed locations.

You need to convince any remaining inhabitants of the chapter houses to either leave or follow your leadership. This may include Player Characters, and you may have to fight the current Chapter House head or other members if they are active, as Iron Falls' normal rules entail. If no one rises to the challenge in a given location, you take the title of House Head for yourself. That said, as it's an independent organization, none of the village-nin should be interfering - the current roster entails that it's filled only with D-rank ninja. If no player arrives to stop you, you'll have to defeat at least three of the stragglers, which have full access to the Ninjutsu Library and one elemental library each.

That said, if you are challenged by a Player Character and lose, forfeit, or run, you fail the mission.

Mission name: Reforging.
Mission rank: C - Special Repeatable. [Quest]
Objective: The dead Iron Falls can be made into something other than its broken, former self. And who better to do it than the one who finally put a stake in it?
Location: Kiri - City || Konoha - Dense Forest || Iwa - Gisei Lake.
Reward: 300 Ryo + 1 EP.
Mission Description: Once you have financial and social control of the organization, reforming it is key. Taking over something and then letting it sit would accomplish just about as much as letting it rot under any other leadership.
Development References: Iron Falls. You must have completed "Cleaning the Rust" in order to take this mission, as well as "Iron's Fall" for the same location if taking it in Iwa or Konoha.

Mission Details: Unlike most Quest Missions, this mission can be completed three times by the same person so long as it is performed in the three listed locations.

Now you must deal with the logistics of reforming an entire organization; eliminating opposition has made it a considerably easier task. This mission is about what you plan to do with Iron Falls and each of its respective chapter houses, as well as how you allocate the ample but finite resources that it has access to. If the new aims are conspicuously not in alignment to the original aim of the mercenary corporation, you'll have a lot of explaining to do, and being completely contrary to them would make you fail the mission - very little could convince this benefactor at such a point.

When you complete this mission a third time, you can change the name, contract, and other details of the organization to whatever you wish.
