Serah and Noctis are then surrounded by Daemons. This time Serah steps forward shielding her brother and raises the ring initiating cross fusion with an Astral
" When distant souls come together the light of the heaven star is revealed , Cross Fuse "
Serah summons the Winged Lion , Madeen and fuses her soul with it giving up her physical form for that of the Astral's becoming one with it. Madeen/Serah then spreads her wings scooping up Noctis and heads to the location where their allies are revealed to be waiting.
Prompto then alerts of something approaching them from the air , fearing it may be a Daemon they draw their weapons. As it drew near it is revealed to be an Astral of holy energy , and is also carrying someone. Madeen/Serah then lowers the person to the ground. That person is then revealed to be Noctis.
His friends then greet him " Is that you Noct ? "
" Yes "
" what about your sister ? "
" Serah had given up her soul to the Astrals allowing them to use her body to aid me , the time has come to make a stand and reclaim our home. "
The four of them then suit up and travel to their final destination Insomnia with the aid of the Astral Madeen " allow me to cut you a path. "
Madeen then slams the ground releaseing a burst of holy light allowing Noctis and the other to pass and continues to shield them until they reach the Citadel.
At the Citadel Ardyn blocks their path and pits against the Infernian , Ifrit against the party. Madeen then challenges the rogue Astral revealing another part of the prophesy.
Disturb not the harmony of light and darkness ,
lest these forces wreak destruction upon the world in which they clash ,
the force of Light shall arise to quell the fighting ,
alone its light will fail ,
and thus the earth shall turn to the night sky
O Chosen One, into thine hands
Ascend into the stars and bring back the light.
Madeen is then defeated , then when things look bleak for the group a sword falls from the sky. It was Bahamut lending a hand to the chosen king. With its help hostile Astral is defeated. Noctis then approaches a fatally wounded Astral which then reverts back to its human form the summoner Serah. Much to the shock to Prompto. With the last of her strength she entrusts her ring to her brother " bring the light back to this world "
" No this role falls also to you sister , together we can change the future."
Noctis instead closes his sister's hand on the silver ring " blessed light of the stars return my sister's soul to me "
Serah then awakens having completed her ascension now she holds the power of the gods inside her given birth to the world's first summoner.
" Brother , I herd your voice call out to me lets bring back the light together. "
The five of them then enter the Citadel " the throne awaits and Ardyn as well , lets put a stop to this darkness " Noctis then stops before the throne room doors and asks Prompto if he still carried the photos they had taken on the journey. Showing Noctis several of them he takes one a picture of each one of them in their younger years before the war , before the darkness overtook the world.
Noctis then opens the door to the throne room and inside he sees three inert figures " what is that " his companions then ask. Upon closer look it is revealed that one was his father , another was Lunafreya , the third one was Ravus. Seated on the throne was Ardyn who then tells the party " I am afraid you are out of luck , the throne brings you here but it seats only one. "
Serah then speaks out " No...The seat belongs to Noctis , the rightful king , not to you daemon " Ardyn then steps his foot on the chair. " Ah , Noct and Serah its been a long time... How long had I waited. Longer than you both ever know. Tonight the dreams of those of royal blood will come to an end. "
" talk about a grudge , eh Noct will Adryn still sit the throne ? "
" not for much longer this is my ascension " Noctis then reponds.
Adryn then fires a spell at Gladiolus , Ignis , Prompto intending to incapacitate them then vanishing telling Noctis to meet him at the palace gates. Serah then raises a hand and casts shell protecting the three.
They are then surrounded by Daemons Serah then tells her brother " go this is your fight "
Noctis then goes after Adryn , while Serah calls to her allies " we must protect the throne and the crystal till the king's task is complete. "
After defeating Ardyn , Noctis, seemingly not wanting his friends and sister to witness his death , orders them to stay outside the throne room and orders them to walk tall. They stood outside to fend off the daemons as Noctis ascended the throne.
After sitting on the throne , he called the spirits of the Kings of Lucii. Each spirit "attacks" Noctis to be absorbed into the Ring of Lucii , each one progressively weakening Noctis and nearly killing him before the ritual was complete. Noctis was able to muster all his strength to stay alive for the final spirit to seemingly finish him off. When the ritual is complete Noctis appears in spirit form alongside Regis , Luna , Gladiolus , Ignis , Serah , and Prompto to confront and deliver a final blow to Ardyn's spirit, forever vanquishing him.
Outside the throne room Serah struggles to hold the line keeping the wall active around the throne room evuentually the Daemons break through just as the entire area gets engulfed in light a single pillar of light shout out into the sky from the crystal shattering the darkness and destroying all the Daemons in the Crown city.
" Its finally over "
With this, the prophecy is fulfilled and light is restored to Eos...
