So if anybody is still undecided I figured I might as well weigh in on what might be the themes of the various choices alongside a few pros/cons.
[ ] By Van Hal's side. Whatever happens.
This has Mathilde standing watch over Van Hal, and is the type of loyalty that'd see her take on whatever dammed souls emerge from the shadows of Sylvania for small kindness of allowing her liege to die as he lived a
man. It
might give her a trait that provides bonuses to fighting alongside those of the Van Hal bloodline, and/or undertaking personal missions in their name.
[ ] A battle still rages. Throw yourself into it.
This would make use of the awe the Stirlander soldiers were showing to Mathilde to rally them, but will probably give her the wrathful trait, and does nothing to fix Van Hal's circumstance.
[ ] Somewhere in that town-turned-battlefield is Brother Kasmir. Leave Van Hal's side. Find him. Sigmar will heal Van Hal.
This has Mathilde working to fix the problem of Van Hal circumstances, and will improve the morale of whatever Stirlander soldiers she encounters so long as she stays up, but is absolutely a risky decision.
Given it has Mathilde ending with the belief that Sigmar will heal Van Hal she'll probably be frantically repeating whatever hymns, or verses she can recall that are associated with Sigmar, and her deeper connection would increase the odds of him hearing the prayers of one of his children who isn't ordained, but at the end of the day anything happening depends on whether, or not Ranald has Mathilde's back.
[ ] The plan exists independently of Van Hal; if necessary, it will outlive him. Take command.
This has Mathilde valuing the cause over Van Hal personally. It would probably clamps down on any panic occurring from their leader going down, and get everyone doing what they know they should be doing, but either due to the chaos, or panic among the ranks might not be going on.
