Neither does Isen, that I can tell, nor any of the grogs. If taking a large contingent is something that is important to a plurality of the council members, and all the council members want to ensure that there is a friendly Flambeau primus, maybe a council should be re-convened and methods to seek transport of a large group quickly to and from Castra Solis should be secured and discussed with the possibility that covenant resources brought to the task at hand, or something.
Right now, I feel like Ron Weasley in The Chamber of Secrets after Crabbe and Goyle consume two tainted cupcakes floating outside the great hall: "How think can you get?" This shall be my last warning generally on matters of this nature, let this be a warning going forward. If you attempt to solve problems with brute force expect smack downs. Stories are generally about political maneuvering. And while the three characters involved here are primarily military beings, they should be past Hermetic childhood and see things have deeper levels. If it seems sensible that one should go to Castra Solis to elect a Primus and one knows that there is competition and a side not friendly to your side, which I've either said flat out or strongly intimated, then travelling directly is foolhardy at best and catastrophically risky at worst. Your adversary is not stupid, but he isn't going to risk that in your naïveté you decide to travel overland, and will have tried to cover multiple bases. Do not play into your enemy's hands.
There is a reason I announced that the ReTe vis source is 6 pawns per season, not per year. I believe there is also a stock pile of this resource. This path is also not without risk. You can choose the risk you wish to take, of course, but those risks will shape the saga moving forward. I realize that the wiki isn't up to date, or current, but in many ways, it's reflective of the saga, and illustrates that the covenant as a whole isn't really well managed or run, which you know, maybe is another thing that should be discussed. There is a reason for every action I have taken or not taken. I do very little as a SG because the characters are Hermetic adults. I base some of what I do based on your actions or inaction.
I'm not upset with any of the actions, but I feel I must be incredibly clear here: If you go overland, people are going to die. Even if you try and get to a boat, people are going to die, because there's a lot of overland territory still to be covered. It is quite possible that a magus will die, I'm not going to pull punches here. Your characters should begin realizing that the enemy they face, while he has a face, also has the coordination of an entire House behind him. A House that is otherwise unassailable, and has hundreds of years of practice in creating evidence that suits them and quickly destroying evidence that does not. Military men should understand this principle of Sun Tzu implicitly: "If your enemy is superior, evade him. If angry, irritate him. If equally matched, fight, and if not split and reevaluate."
