My son and I have been enjoying the new game, Baldur's Gate 3. He is much further along than I am and so is his D&D 5e group. One of his favorite characters is Karlach, the tiefling barbarian. I admit, she is great. Karlach is this 6ft+ tall tiefling warrior goddess who is also one of the funniest, most optimistic characters in the game. My son calls her a "cinnamon roll" because of how sweet and fluffy she is.
When your character is idle she will be humming to herself and dancing in place. She says things like "fuck! It is great to be alive!" and when she runs into combat she laughs. She calls everyone "soldier" and loves it when you stick up for the underdog, kids or find ways to keep the innocents alive. She has every right to be angry and bitter; instead, she is cheerful and optimistic.
And sadly...she is also dying.
Spoilers ahead for the Baldur's Gate 3 video game.
Karlach has an "infernal engine" for a heart. It works great in Hell, where she was fighting in the blood war, but on the Prime Material, it is burning her up from the inside. One of your quests is to find a way to keep her from burning up. You can, for a while (and it is worth the effort!) but in the end...well the Devil has their due.
There are a lot of different endings for all the "origin" characters, but Karlach's was particularly bleak. Her happy ending was to be able to say she loved everyone before burning up, leaving only ash.
What did Larian Studios do about this when players started complaining about it? Simple they did what any good studio would do. They pulled back in the voice actress, reshot Karlach's ending with all new material, and patched it to the game in a matter of DAYS.
You can see her new "happy" ending here.
Personally, I love the idea that she and Wyll go off together since their backstories are so intertwined. If I do another run-through of this game, I want to do it as Wyll with the purpose of seeing what I can do to save Karlach. Karlach would never do it for herself; that is not who she is.
BUT. Even with the "they lived happily ever-after in Hell" ending my son and his group are less than happy with it. So we were talking about it one night while playing BG3.
He wants an adventure for his party where they go to Hell to rescue both Karlach and Wyll. He wanted to know if I had anything.
I told him that was a silly question.
I mentioned the adventure A Paladin in Hell does this, and it has somewhat the same premise as the newer D&D 5 adventure (and Baldur's Gate 3 prequel) Descent into Avernus.
I told him to use the basic outline of APiH, use details from BG:DiA, and make it a mission to rescue Karlach and call it "A Barbarian in Hell." However, in my current run-through, Wyll has rejected his warlock powers to become a Paladin. So I guess it still works. I half-jokingly have called this "No Sleep Till Avernus" with my son.
In this adventure, Karlach and Wyll are defending a piece of Elturel that has remained in Avernus (let's say it was the temple in A Paladin in Hell). The characters in Baldur's Gate 3 are limited to 12th level. "Descent into Avernus" takes the characters from level 1 to 13. The AD&D 2nd Ed "A Paladin in Hell" is for characters 15-20 level. So then A Barbarian in Hell is for characters 13th level and above.
The motivation for most D&D adventures is glory and gold. The motivation for A Paladin in Hell is "the greater good." For A Barbarian in Hell, the motivation is "Save our friends." And that is a good motivation, really.
Besides, if the roles were reversed, you know Karlach would have saved your ass a long time ago.
