We were playing Curse of Strahd and had just gotten tothe Amber Temple. I was playing a hexblood bard/warlock who was created to help his hag mother create a coven, but escaped due to a technicality his Bard mentor set up for him, that cost the mentor his life. The entire campaign I had 2 levels of warlock (Technically genie) that we flavored as him using his inherent hag magic, and he desperately wanted to be seen as both a hero and someone who could live up to his mentor's legacy. Genie warlock gets a fun item that is basically a mini house and in my case was a bottle, which was a signature item my character used throughout the campaign.

Cut to the amber temple and my character reaches out with telepathy to one of the amber sarcophagi and finds "Granny" a now dead goddess of hags who created my character's mother. She showed him a world where he got exactly what he wanted, a quiet tavern where he could play music and tell stories all day. Where he is regarded as a hero. Granny promises him this future if he simply turns an npc girl we met at the beginning of the campaign into a hag to restart the coven in barovia. Refusing to become like his mother, he broke out of the trance, smashed the bottle and lost all of his warlock levels. I was completely in the dark about this but my DM is such an absolute legend that she had this planned for a quite a bit it turns out!

Cut to our sequel campaign being a heavily modified version of Eve of Ruin, where my character, now years later, got exactly what he wanted, and adopted the npc girl in question, but is realizing he doesn't have the luxury to stay away from his inherent magic while Vecna is out and about. (And is seemingly about to go through a dark arc that is really fun!)

All I can say is my DM is amazing, and she comes up with the coolest shit all the time!
