(A/N: I know Au-Ra aren't Dragonkin but in this fanfic, I will make it because it fits. Also, bend some lore of FFXIV.)
The next day Vincent awakens and walks to the hall and sees Arngeir and three other praying or at least it looked like that to Vincent. "Ah, you are awake. I'm sorry the other three don't talk out of fear of overwhelming you with their mastery over the voice," says Arngeir and Vincent asks, "And my friends?" "They are either sleeping or outside training. And that mount of yours is quite intelligent. It tried to fly after beginning to feel the wind pass through it. I was really impressed by it when it began to fly some feet over the ground," says Arngeir and Vincent says, "Aye, they were raised to fly in Ishgard but they first need to accustom to the region they live and feel the Aether Current in it and they will be able to fly."
"Aether?" asks Arngeir and Vincent says, "That's how my people call Magicka." 'Just that it isn't completely true. I have two tanks one for Magicka and one for Mana.' "Quite interesting to bad you don't have a second one from the other gender or you could start a farm making much money with them," says Arngeir and Vincent says, "How about we talk why you called me." "That's quite simple we want to teach you in the way of the voice," says Arngeir and Vincent says, "That simple?" "That simple. We can't control you Dragonborn. No one can that's why we will teach you the way of the voice but before that, you have to pass a trial we make all Dragonborn do. First, you will learn the second word of the Unrelenting Force. Ro from Master Einarth. Ro means balance," says Arngeir and before he stopped did the Greybeard beside Arngeir say "RO" against the ground and Vincent began to read it repeatedly until it began to shine and it burned itself in his mind.
Before Einarth could share his understanding with Vincent he shouted unconscious "FUS RO!" into the air shocking all four and Arngeir says, "Quite impressive you didn't need Master Einarth's understanding over the word. It seems the Dragon Blood and Soul are strong in you."
The three other Greybeards go out to the courtyard and Arngeir says, "We will continue outside." "You said my Dragon Blood and Soul are strong," says Vincent and Arngeir says, "Yes, my brother must be feeling the same. But don't let it get to your head. Many proud men died because they thought of themselves better when they weren't."
They arrive at the courtyard and Arngeir says, "Now we will see how fast you can learn a new shout. Master Borri if you please." Borri shouts "WULD" against the ground and Vincent begins to read it, while Arngeir says, "Wuld means Whirlwind. It's the first word of the Whirlwind Sprint. Each Thu'um is made out of three words. The more words the stronger it is." Vincent like before shouts, "WULD!" and begins to sprint against a wall.
Mina who was in the courtyard was watching them and rushed to help Vincent when she saw him crash into a wall. The Greybeards rushed over too and Arngeir asks, "Are you alright Dragonborn?" "Yes, but now I feel empty for some reason," says Vincent and Arngeir says, "That must mean the Dragon Soul you absorbed before is completely used. You can learn the Thu'um in two ways. The first is like us. Reading and meditating over the words and it's meaning. You have a clear advantage because you are the Dragonborn and can learn them quite fast not like right now but with our help and understanding over the words, you should be able to learn the most Thu'um from us. Like how to Clear Skies like I used yesterday or Become Ethereal and many more."
Mina helps Vincent up with the help of the Greybeards and Arngeir continues, "And then there is the way you just used. You kill dragons and absorb their souls. You can learn shouts instantly thanks to their knowledge over the voice. It might look like the fastest way but it's also the dangerous one. Since you absorb their soul it can happen that your body becomes corrupted and your Dragon Soul might come out and take over." "I don't think that can happen since I'm born as an Au-Ra. We are dragon descendants if we don't go after the old sage they tell the children," says Vincent as he stands on his own again and Arngeir says, "That means."
"Yes, I have before I became a Dragonborn the blood of a Dragon in me and its soul. Even more so as a Dragoon. We get our power from the Dragon blood inside us and the power of a Dragon Eye or at least it was like that. I killed many Dragons before in my hometown. And I didn't absorb any souls back then. Then I kill one here and hell breaks loose," says Vincent.
Arngeir, as well as the other three Greybeards, began to discuss something and the ground was shaking just from the whispers of the other three Greybeards that never open their mouth. 'Now I know why they never talk if they would the world would shake the whole time.'
"Dragonborn a question. Do you come from a world named Hydaelyn?" asks Arngeir and Vincent almost dropped to the ground and Mina was now curious she never heard of something like Hydaelyn before and Vincent asks, "How do you know?" "Our teacher once told us that there are more worlds than just Nirn and that Akatosh made a deal with Hydaelyn. He would give her Eight Dragons and he would get in return a Warrior of Light. Are you the Warrior of Light promised by Hydaelyn?" asks Arngeir and Vincent looks at them and then at Mina and says, "Mina can you go inside if you have questions I can answer them later."
Mina leaves reluctant inside and only the Greybeards and Vincent were outside and Vincent says, "Yes, I'm from that world. I'm a Warrior of Light in-training. I was promoted by Hydaelyn when I died and she needed to sent someone here with Akatosh." "So Paarthurnax told us the truth the whole time. I'm sorry where were we again," says Arngeir and Vincent says, "The trial every Dragonborn has to do." "Right, You have to bring back the Horn of Jurgen-Windcaller. He was the founder of the Greybeards. We make the Dragonborn bring or take the horn from his tomb when one appears. Last time it was Tiber Septim himself that went there to leave the Horn in its rightful place. And now it's yours to bring it back," says Arngeir.
"Alright, just one question who is Paarthurnax?" asks Vincent and Arngeir says, "He is our mentor and lives on the peak of the Throat of the World. You might meet him after you brought back the Horn." "Where do I find the Horn?" asks Vincent and Arngeir says, "Do you have a map it's easier pointing where you need to go than say it and hope you get there." "How true you are," says Vincent as he brings out a map and Arngeir point on the map. Vincent marks the place and Arngeir says, "If you want you can go inside and I will give you a book with the words of power we collected over the centuries. Since you learn fast you can begin in memorizing them."
They enter again and Mina was looking at Vincent suspicious now. She wanted to know what was going on and what this Hydaelyn is. Vincent seeing here staring puts a finger on his mouth and she understood that Vincent doesn't want others to know of it. Vincent follows Arngeir, who gives him one book that was quite thick and says, "This is one of the books it contains useful Thu'ums and how to meditate and understand them. For you, it will be faster than for us. You can read the other after you finish this one. Just be careful not to stray from the path of the voice too much. Dragonborn or not, one day it will catch up to you if you misuse your powers."
Vincent accepts the book and puts it away for now and Vincent walks over to Avulstein and wakes him up and says, "We will be leaving tomorrow morning." "Where are going?" "Ustengrav, it's in Hjaalmarch in the near of Morthal," says Vincent and Avulstein says, "If we go, can we go to Morthal. I might want to meet Idgrod the Younger again. It's been long since I was in Morthal to see her." "We can go but first let's go to Whiterun," says Vincent as Avulstein says, "Want to meet your daughter again." "Yes, and Mina should rest a bit even if it delays our travel a bit," says Vincent and Abulstein says, "Maybe the Priests of Kynareth can help her regrow her tongues. If not then there is still the College."
Vincent nods and bows to Arngeir and says, "I'm sorry that I will leave tomorrow again." "Don't be sorry. You as Dragonborn aren't bound to us. We are only here to show you a path that you can take. You can come and go whenever you want just remember that you will always have a refuge here if you need to retreat from the public," says Arngeir as he gives a key to Vincent and says, "Food will be served at midday."
Avulstein stands up and goes to the courtyard and Vincent begins to read in the book Arngeir gave him. He began and lost track of time while reading it. He put it back and read the next one that went on until he finished all three book that they had and Vincent began to meditate on the words "YOL" "LAAS" and "FO" after almost an hour of meditation he learned one and he kept going every hour that pass he learned to use the word. They were quite weak for now but he didn't expect much since he didn't use a Dragon Soul to learn them.
He leaves meditation and finds Mina staring at him and Vincent asks, "Something wrong? If it about what we talked outside we need to get to my house first." She shakes her head and makes a motion like someone was eating and Vincent says, "Food is ready, really? I thought that just some minutes passed." She shakes her head and points five fingers up and Vincent says, "Five hours really?" She nods and Vincent says, "*sighs* Let's go to eat then."
They go to the dinner table that almost looked like it was made to hold conferences here and Master Borri gave Vincent and Mina a bowl of soup with vegetables. They sit down beside Avulstein and Arngeir, who asks, "How far have you gone?" "I completely read all three books and learned to use the First words of Fire Breath, Ice Breath, and Aura Whisper for now. The shout are still weak and I might still need to meditate on them to make them stronger," says Vincent shocking the Greybeards who regained their calm-self and Arngeir says, "I and the others are pretty invidious of your talent as Dragonborn. For you, it might take hours to learn a word and master it after some hours. For us, it takes months to learn it and years to master it."
"I'm sorry, I didn't want to look down on you all," says Vincent and Arngeir says, "You shouldn't he gave you this talent so embrace it." They finish eating and Vincent goes outside. He sees Avulstein training with Mina while Behemoth was nowhere to be seen. He sits down and begins to meditate again still on the three words of power to strengthen the foundation. Until they hear a roar coming from the west.
