Well, as you know, I can't be familiar with EVERY SINGLE character of these fandoms. At least not yet. So, until I'm familiar enough with all the characters of these fandoms, here are some people who are currently NOT eligible for a diary entry. (I can't write in behalf of them if I don't know them well, can I?)

MARVEL
Characters from "Guardians of the Galaxy" are currently not available. Neither are the Winter Soldier, Peggy Carter or the Falcon. (Sorry!!!! I've still got to watch the Captain America movies again!)

RIORDAN UNIVERSES
Characters from 'Heroes of Olympus' and 'Trials of Apollo' are not eligible yet for a diary entry, except for Apollo.

(I just started on the Son of  Neptune so I've got a long way to go!)

That's it. These are the only characters I can't write for right now.

Apart from that, anyone from the Avengers, Wakanda and Asgard are perfectly okay. Every character in the Harry Potter world is eligible for a diary entry too, along with Percy Jackson, Kane Chronicles and Magnus Chase. As for One Direction, the five lads are fine too :)

I'm sorry if I'm missing out on your fandom. Right now, these are the ones I'm in, but maybe the list will grow longer...

So have fun! I'm taking requests, so if you want a diary entry written by your favourite characters, request now!

I'm only accepting five requests for the time being, so comment inline here.

State which character should write the diary entry, and mention the timeline it should be set in (like Pre-Endgame or after the Battle of Hogwarts etc)

I hope you enjoy this :)
