So, admittedly I come at WHF from a very different origin than most, and that feeds through to not really knowing Karl Franz or Gortek as characters in their own right.
That said, I'm actually glad that both are gone in this 'verse? Hearing them talked about rather than emotionally bonding with them first they kinda come off as a bit insufferably Mary Sue, where the rules of the world bend themselves around the characters because they were just That Cool and could do things through sheer force of how much more Awesome they were than anyone else. It's like not having to play in a world where the GM's favorite NPC is running around saving the world.
It lets other characters matter more, rather than having the chosen ones handle everything. And it changes the context of a lot of future threats- without plot-armored characters using them to style on, they loom much larger as real problems.
The dice have, objectively, spoken - Gotrek is dead and the expedition has permanently lost him and his expertise. But the dice have, just as objectively, also spoken against Gotrek being found among the dead.
His body wasn't shown in story, which means there is still room for an expedition epilogue where he wakes up, badly injured but alive, somewhere underground that no one would have found without crashing into it (in this case literally)... and sees a certain axe.
As long as his final final fate isn't shown in story, there's still room for a miracle, even if Mathilde never gets to see it.
I'm kinda surprised that no one has written an omake yet. In fact, were someone *particularly* ambitious, this would be an amazing point for a second quest to fork off- one where the players are Gortek waking up in a smashed cave on top of a runic ax.
We, too, can create! And I always love reading stuff that bounces off the worldbuilding Boney does, because they are so *thoughtful* about it.
I'm kind of surprised the Press On option has such a strong lead.
I'm honestly seeing this as karmic payback for us getting greedy and spending a week on Vlag at the beginning. We made the decision that we had enough of a safety margin and were willing to risk failure and massacre over a target of opportunity, of course fate is going to bite back. But now we are too far in to back out.
Personally, the worst outcome for us now is a significantly intact dwarfhold that wants to evacuate. We have neither the space not the material to help at all relevantly, and getting a large population through chaos dwarf territory without being enslaved, much less expecting to procure food from then, would be a nightmare.
Best case scenario for us, there are ~50 dwarves remaining and holding the treasuries. We loot, grab all the survivors, and bolt- success on all counts, and within our capabilities to support.
Odd case would be the dwarves basically surviving more or less fine, under siege, but in a nice bubble of reality kept running by their waystone. (Honestly, with Borek knowing secrets, is possible the king of Dum could do something like actively control the focus of the waystone suction to evaporate demons as an at-will AoE) In that case, we restock, catch them up, plan, and maybe overwinter.
Bad case is we get there and it is empty and destroyed or full of gribblies- we stand off, scout with ulgu, loot, and leave.
