I cannot state for sure how any of the other characters would have done anything but my character would have died to protect his realm from war if given a reasonable chance to do so, just as I believe IC another one of the characters had already stated something very similar in private channels. (My character sent letters with this intention included if it was proven necessary)
So two of the four characters involved would have willingly walked over to Solaria and turned themselves in for execution in order to avoid their realm going to war with Solaria? Out of curiosity, did your character or the other such character, at any time in the four hours you were sending messages yesterday, mention this? Perhaps, saying something like
"Arbiter Malus, I would gladly let you execute me in order to avoid war between our realms, if there truly is no other solution to this predicament, but there's no way I do so within the 24 hour time limit you specifried. Please give me a few days to travel to Poryatown, and I will willingly let you lop off my head so our realms may continue to exist in peace and harmony." I mean, if you did, then wow... kudos to you and your character for being so dedicated to maintaining peace in the Lurias. I guess.
The issue in my opinion is not that the consequences are that the ruler be to go to war, but that the character is manipulating an OOC timeline to create IC reasons for going to war. As you clearly stated, and everyone is aware (on an OOC basis, and some IC) that Malus always intended to go to war anyway. But by creating a timeline which is impossible to fulfill on an OOC basis, in order to have IC justification for an action, is ludicrous.
So our characters are not allowed to make impossible demands of others? Even if the characters
know that such is impossible? Maybe Malus specifically wanted the demands to be impossible to meet, and concocted the entire demand scenario as nothing more than a stage performance to gain support for his side? (Which, come to think of it, is exactly what you're suggesting he did...)
If Malus had simply declared war without a wait, then he would have far less allies than he does now(and have made many enemies). If Malus declared war with a 3 day wait (thus giving the other side time to actually log on and respond), he would have far less allies than he does now.
This is extremely speculative, and requires you to speak authoritatively on behalf of all these other players. From what I can see, given the fact that pretty much everyone in the Lurias, and most of the people outside the Lurias, knew this war was coming, I can't see how declaring it right away would have lost him any support.
However, by placing a deadline which made it impossible to respond to from an OOC point of view due to players having a real life,
Again, for curiosity's sake, how many of the four accused nobles participated in the discussion in the next 24 hours? Was it actually impossible for any of them to respond? (Although, how would you, or I, know that it was really impossible for them to respond, unless you know them OOC and they told you they couldn't. A failure to respond IG could simply mean they chose not to respond.) For those who did respond, did any of them state IC that their characters were willing to comply, but could not do so within the timeline specified? If they did, then was the only reason that the demands couldn't be met, maybe with just an extended deadline (no pun intended, really...) , that some of the four characters involved did not get a chance to participate in the discussion?
he has established a justification for war, which as players we know is completely bogus, but our characters can consider legitimate (because a demand wasn't met, etc...)
Can you not claim that his casus belli is illegitimate and unjustified, as he made demands that were impossible to meet? And in doing so, pull support away from him? After all, he's obviously an irrational warmonger who is not at all interested in peace. If he wanted peace he wouldn't be making such ridiculously impossible demands. After all, he didn't even wait out the full 24 hours he said he would. I mean, you *wanted* to comply, right? But it was simply physically impossible to do so. "Abiter Malus set arbitrary and impossible conditions designed to lead both of our realms down the only path that was acceptable to him: Civil war among the Lurias. Etc., etc. ..." Seems to me that maybe such a stance of your own could pull some of his allies away from hi, and bring them to your side. After all, no one wants to side with an irrational, and possibly insane, warmonger.
Thus, Malus has established a war with plenty of support on his side when IC wise this support could never have been found through legitimate IC action.
What do you mean by "legitimate IC action"?
