Alright crazy Fates Revelation AU time :D Remember Anthony?! Long AU and backstory ahead:
So let’s say he was really born a Vallite, but definitely not yet able to have known the first king of Valla or Anankos before degeneration. His family generation may have actually served Anankos as personal aides. By the time Anthony was born, the kingdom and its people were already on the verge of destruction due to Anankos’s madness. Anankos was said to have slaughtered all his people (except the royal family who escaped), but may have decided to enslave Anthony (who was last of his family alive) due to their previous ties (Anankos may have even found it amusing to have a human ‘pet’).
This leaves Anthony continuously threatened, with no way out except death. Anthony is sent out to perform many dirty and undermining tasks to stir up trouble and hate within Nohr and Hoshido. He may have developed his talents in trickery and deception in this manner, knowing he can never be trusted.
He starts dreaming of a hooded blue haired man, speaking to him words of encouragement, but they always turn to nightmares where he is held down by the oppressive power of an all-seeing monster.
Anthony is in a state of constant turmoil, hating himself for what he has become. He starts messing up simple missions, drawing Anankos’s ire. Sick of the child, Anankos assigns him his supposed final task - killing Corrin.
Now to bend the plot: instead of Anthony going graaagh Faceless at the end, just at the point before entering the ruins (where the trap happens), he actually sees the strange blue-haired man himself, speaking through Corrin, hearing the words:
I trust in you.
Anthony hesitates, and in a moment of mental clarity, finally breaks free from control and warns Corrin about the trap. Surprised at this turn of events, Corrin and his army still forge ahead to clear the failed ambush. Meanwhile, Anthony is taken as prisoner and kept under close watch. He never attempts to escape although he clearly seems to be fighting something internally, and his knowledge of the Vallite forces helps the army’s progress.
Fast forward aloooooot: With Anankos overthrown, Corrin has been crowned the Emperor of the three realms, with the other royal families still lords of their own kingdoms;
Azura and Shigure aid in ruling the kingdom of Valla. Everyone is free to move amongst the kingdoms, but there will always be new troubles that arise from a unified realm…
So now the actual AU lol - Anthony now acts as part of the Royal Guard and one of Corrin’s personal retainers.
Despite being one of Corrin’s trusted aides (ironically), Anthony still finds himself being kept at a distance by others due to his past.
Out of old habits, he still deals in secrecy and lies, but now uses his abilities for the good of the kingdom. Meanwhile, Lilith has been made an ambassador. She is known for her iron bottomless stomach, and is beloved due to her cheery and selfless nature.
These two will go on their own quest through the realms, aiding the people and resolving conflicts. Kana will tag along as a princess-in-training-who-kicks-butt, with Dwyer as her assigned (by Jakob) butler. Anthony initially finds the company outright annoying, and in moments of weakness still finds himself poisoned by the whisperings of a mad Anankos. Lilith sees past that and tries to get him out of his shell and to move on from his past. What will this new future hold?
To be continued?!
