The title is clumsy, because it's hard to explain without referencing "The Day the Deathwing Came" in WoW.
In it, an NPC tells you a story, but instead of watching it or reading about it, you play that character in the story. There are two direct follow-ups to this particular quest, and you play the two NPCs who tell you those follow-ups.
What other games and quests who this? (It doesn't have to be as silly or as good as my example.)
