@Juniper I disagree that death should be entirely off the table, but I do think it should be intentional on the part of the player. An OOC check-in of “Hey now, if we keep going down this road, then death is very much a potential outcome” would be something I’d suggest, even if you’ve previously established that certain acts, areas, character types are more likely to provoke lethality.
Now, this doesn’t necessarily suit all game genres and types. To me, it probably suits a WoD game, or similarly mechanically driven game, than something like your high politicking Lords and Ladies game. Though I also disagree with the idea that character deaths should be solely dedicated to wrapping up a character in a respectful way. Awesome would be the ideal, sure, and it should serve the game’s story, but a death that’s inadvertent and unexpected IC is prime story fodder.
I can’t help but raise the death of Mollymauk in Critical Role’s Mighty Nein campaign as an excellent example of unexpected death impacting the story in a way that might have been unsatisfying and distressing to the player in that moment, but became foundational to the story as a whole.
ETA: But as with all high risk stories, you’d need a strong level of trust, rapport, etc, etc, etc.
