Hmm, it definitely brings forth a lot of questions to be answered. SL likely couldn't successfully hold a large scale event at the moment. Instead of a civil war, it might be best to scale it down to a single mission with one group attempting to safely escort the Tori Miku and one group attempting to kill her on her way to Tori no Kuni. It would shorten the whole thing and perhaps make it more doable/only require say 4 people in total to manage with an extra moderator to keep an eye on things.
Sl can't "handle" such a large event?
Pockets full of posies it can't! What you can't do is suddenly start a large set of civil war battles. There is no logic to such an immediate scale-up. It makes sense for it to start small in the normal flow of things, and a week is way too short of a time in my opinion. A week per MISSION, maybe, but for the entire event?
Nah, I think a month or even 2 is more reasonable for an Event of this sort. It starts small with the realization that Tommi is back and looking for someone to replace the contract; in other words, someone to carry on the lineage. Some are overjoyed, some not so much; until Tommi finds a suitable replacement, there is no need for a mass taking up of arms, as an army of regulars vs Yellow Flash = Madara busting down the stall door while when you are just getting started.
Tommi obviously might be the last of them, so sending a few spies to tail Tommi and keep an eye on progress would be a good start. They will want to start securing mercenaries and such early on, and send out NPC's (or even players directly playing a shinobi from that land) to attempt to recruit from the villages.
As the incumbents shore up their military power, those seeking to restore the lineage would warn Tommi of the build-up, leading to their subsequent arrest/imprisonment. Tommi, if he has not found a successor even by then, will have the additional issue of having to possibly force the lineage back on the current ruling elite, and may want to do a little recruiting of his own. He'll have to prioritize taking out his opposition and finding a successor.
If for some reason he still has not found a suitable successor, the Tuni sort would send some of their better mercs to try to take down Tommi, well aware of his reputation(s) and intending to do it ambush-style (similar to when the Yellow Flash was ambushed in the SL fanfic, but with a likely different outcome).
Tommi likely survives and at that point will have to blah blah blah as it goes on.
The logic conclusion to the event requires only two things:
` Tommi to find a successor who accepts the role
` The ruling elite accept the new successor, willfully or post-mortem if needed.
Rules for the Event, geared towards the fighting portions:
**** If a player character dies during the Event, then their character is locked in death until the end of the "mission" that they are on, the mission of which can last no longer than 2 weeks at a time regardless of the amount of active posting.
**** Each participating character can only use 1 enhancement (Invisibility, lightning release armor, susano'o, sage mode, earth grudge fear, etc.) at a time during the Event. What counts as an enhancement is very broad, but the GM for the Mission ultimately decides disputes.
**** To keep posting disputes brief, the two or more parties involved in the dispute may present their case via PM to the GM ONCE before the GM makes a decision and posts it in the zone/board, etc.. If more than one is sent, then only the first one recieved will be counted. These must be resolved within 48 hours, and if the GM does not post a decision by that time, then the original poster reposts, omitting the challenged material, and then the match continues without further delay. If this occurs more than once in a Mission then the appointed GM will be replaced.
**** Players cannot play characters from both sides in the same Mission, even if the characters are NPC's, without the explicit permission of all of the other players in the Mission.
**** While this Event is technically IC, consequences such as death are altered in order to limit excessive risk to player characters only. Specific NPC's die when killed, regardless of which side they are on, unless revived by a player character.
