Summary
On the ten year anniversary of his arrival to Mondstadt (or his departure from home), Kaeya looks at everything he’s done, everything he’s lost for this foolish mission, and decides that a decade has been enough. He retires the title of Prince, gives up on his mission, and permits himself to live the lie he’s weaved. He’ll be Cavalry Captain Kaeya, of the Knights of Favonius, and nothing more.
It has been said by many, that the surest way to get what you want is to announce to the fickle gods that you no longer want it.
The very night Kaeya retires the title of Prince of Khaenri’ah, A child falls from the sky.

Summary
She looks at him, focusing her will into reaching out and brushing a lock of his hair out of his eyes. “The last time I existed, I was holding you. Sometimes I forget, and start to look for you. My will is strong. Garp forgets too. We wake up and start looking for the baby. For you, Ace.”
“I’m not a baby anymore.”
“Logically, I know that. but only in the sense that it has been nine years since I stopped existing, so you must be nine years old now.” She cups his cheek. “Sometimes I look at you and have no idea who you are.”
The sentiment strikes a pang of fear into Ace and when he looks at Rouge she offers no comfort, staring at him with the same aloof expression she’s had all his life. He had thought—He had thought she was just reserved, too cool to react. Now he’s seized by the fear that this might mean she’s just been… ambivalent to him this entire time.
Ace feels tears rolling down his cheeks, and it’s only because she isn’t real, that he lets her see them. “I’m your baby,” he says, choked up, “Mama, I’m your baby.”

It really, really hurts.

Summary
Contrary to popular belief, having your father adopt any idiot he comes across does not automatically lead to peace and harmony as a thousand-strong crew. It feels like the water only ever stills when Whitebeard’s about to throw another boneheaded rookie in to disrupt it. Then everyone goes to Marco to whine about how they don’t want another brother. And this brother is clearly too much of a handful. And can’t you talk to Pops, Marcooooo.
The crew is a powder keg on a good day, but like hell is Marco going to let Portgas D. Ace be the thing that sets it off.

all that it touches to wonder by cynassa

Summary
Life after war has much more politics than Gimli thought, and much less Legolas than he would like, but the latter he knows (or believes) he has to get used to. Or: Legolas leaps, occasionally stumbling, into a new age, while Gimli can't see the wood for the (green)leaf.
"How do your people court then?"
The question was not as abrupt as it would seem, firstly because the news that his brother was courting had clearly left Legolas in deep thought for a number of days, secondly because Legolas had long ago confessed his curiosity about the lives and customs of Gimli's kin, and thirdly because Legolas' grace was well-known to be in his light feet and not his manners.
However, Gimli saw no reason to let him have his own way entirely. "And by my people do you mean the Longbeards, or the Dwarves of Erebor, or the wandering mender that I now seem to be?"
"I meant," Legolas said, "wandering jesters."
