King drops his wholesale; His fantasy was about being a tyrant who destroyed his enemies, which is inherently destructive in practice. And with him realizing how much power he DOES wield now, and must be responsible over -both in his friendship with the Collector and status as a Titan- it makes sense he just abandons that completely, especially in foil to a certain witch hunter. And he abandons that fantasy because it wasn't actually what King wanted, and he's figured that out now. His fantasy admittedly started off as a delusion fed by Eda, too.

Luz still keeps hers; She's just learned to maintain a healthy balance, deciding when and when not to embrace and pursue it. This can be attributed to Azura being far less about destroying enemies; Aside from the Gildersnake, it seems most of her stories are on the friendlier, mundane side, with things like sports and growing plants. But we do see how even the former can get distorted and hurt others, hence Wing it like Witches. Likewise, Luz holding onto her fantasy is her way of keeping her father Manny alive, and embracing her weirdness, who she is as a person, etc.

There's a dichotomy with these siblings' fantasies, and even the origin of them; King's came about as Eda humoring him, but not knowing when to make a distinction for her kid. Meanwhile Manny gave Luz's fantasy to her, and it was about keeping her spirit alive, and not just the fun... But the fun matters too of course. So Luz's relationship with her fantasy is her relationship with Manny, because of its inspiration in Dana receiving Pokemon Red from her father before his death. So she can't just drop it, Luz needs to learn to live with it healthily like Eda learns to live with the curse, etc.

And it's a way for Luz to continue her living relationship with her other parent Camila, who understands now, and wants to cultivate fantasy in her daughter and even herself again to bond over; Something Luz initially refuses out of self-loathing, and a misguided attempt to reconnect with Camila when she thought the opposite -pursuing fantasy- was what pulled them apart. But it was because of the death of their wonder and the enforcement of that by the system, and mother and daughter finally rekindle their light in For the Future together.

You can also see Titanlights' relationship with fantasy through the Titan, another parental figure whom is mutual for these sibs. The Titan is the setting and thus embodies a lot of the show's themes; The Titan is Just Some Dude after all of the insincere, destructive hype of being a God. And this is how King wants to follow. Likewise, the Titan explains to Luz that she needs to forgive herself for her dream's unintended side effects, and by passing his power onto her briefly, allows Luz to live out her dream as much as she can, and remember that afterwards. Luz internalizes both the Titan's mundanity and encouragement for her healthy relationship with fiction, and King gets his new dream by seeing his dad's spirit in action, as well as a personal message; I loaf you.
