We look back before the Calamity where most people are trying to get some sleep. We then check on 100 A.C. and see how much fun it can be trying to communicate with people who only appear when you are doing oddly specific actions.
Link remained functional long enough to change clothes at the behest of Robbie and Daruk. Urbosa's suspicions were confirmed after Link had washed off and changed clothes. He was handsome. Zelda and Mipha both had a moment where their breath stopped before they looked away. Urbosa noticed. The Champions and Zelda were offered a few cots by the Sheikah so they could get some rest.
Of the two cabins they'd been given, they put Link in the one with a single entrance to watch. Revali and Mipha were on Link-watching duty at the moment. It wasn't too eventful and neither person was sure what to do about Link. They both awkwardly watched the figure on the cot which had decided to huddle under the blankets. There was the occasional sniffle from Link and a miserable aura prevailed in the cabin they'd selected.
Mipha's turn had come. Revali stuck around to back her up in case of an emergency instead of heading to bed. She leaned her spear on her shoulder as she looked at Link.
"Link? Do you want to talk?"
"Ifyo ufin dtheancie ntevil I nee dt oslayI mgo nnane edam inuteit sbee nalo ngday."
Mipha quietly turned to Revali and asked, "What did you do? He was more cheerful when we were trying to kill him."
"I didn't do anything. It just started crying after it had been writing stuff. Ask Purah and Robbie, they were the ones who were writing back." Revali folded his arms. "Maybe he's having a crisis of conscience or something?"
"I don't think he's Ganon. There's the Sword and he just doesn't seem evil." They could have kept talking all night if there weren't people that might be awakened by the noise. There wasn't much they could say about Link that hadn't already been said. "Maybe we could get a luminous stone nightlight in here?
"Good idea. It will be much easier to see any suspicious behavior."
"It might help with that, too. My little brother sleeps much better with the one I carved for him." Revali opened, then closed his beak. Anyone else would have been chewed out. Mipha was way too kind sometimes. Both assumed combat positions when they heard a sound outside.
Both relaxed when they saw it was Urbosa. "Vasaaq. Zelda should be waking up soon and the researchers are almost done loading the pack horse with what marble they could find. Is there anything to report here?" There were missing chunks of flooring even after the search.
Revali shrugged, "No, it's just been like this our entire shift. Was it the same for you and Daruk?"
Urbosa nodded and regarded the miserable pile of blankets with blond hair and a purple hilt sticking out of it. Only those who knew Urbosa well would recognize the thoughtful look in her eyes. "Mipha, I'm guessing that you've tried helping Link?"
"I have."
Revali said, "This is a shameless ploy to gain sympathy if you ask me."
Urbosa held a hand to her chin in a thoughtful way. She left and returned minutes later with a bowl of leftover soup. "Link? You missed dinner earlier." She set the food down next to the cot then took a seat on the bed on the other side of the cabin. The scent of pumpkin wafted.
It wasn't long before Link ate the soup and the atmosphere got marginally less depressing. After waiting for a while, Urbosa got out a pencil and some paper and scribbled on it. After some more waiting, she had Link drawing... something. Even Revali was trying to get a closer look. It was a step up above children's drawings. Link had settled on some glorified stick figures.
The first picture seemed to be Link with the Master Sword and five other people. It looked like his armor and he said his name while pointing to it. One had wings, the other was probably supposed to be a Goron. It was hard to tell about the rest. There were doodles that looked like the Divine Beasts.
The second picture had a giant black evil-looking pig-shaped scribble on one side. The doodled Link and one of the long-haired people were on the other side with the Beasts. The Divine Beast sketches were firing lasers at Ganon. The lines seemed like lasers.
The third picture had the sword on the ground next to the long-haired person. It looked like Ganon had Link grasped in a claw and was eating him. (Or Link was climbing a really weird tree.)
The last picture had little caricatures of what looked like the Champions and Zelda. The Zelda stick figure looked a lot like the long-haired stick person on the previous pictures. The doodle that vaguely looked like Daruk appeared to be throwing something. What looked like Link was on the other side and floating in the middle between them was a blob with the sword sticking out of it. Some small lines behind the boulder sketch indicated movement. It was easy to tell what that was depicting.
Before hitting the road the next day, Zelda 'accidentally' dropped the last picture on a fire before Purah could get a closer look. She really didn't want her father to find out they'd nearly killed the person with the Master Sword by chucking a piece of floor at him.
Link had, in the time after meeting Urbosa's spirit, come up with a plan to see if she knew about the location of the Master Sword. It was like the manner in which he'd asked Daruk if he knew where to find the sword. This was a less hazardous plan than the one for talking to Daruk. Link was waiting for Mipha and had spent the entirety of his saving-for-a-matching-helmet fund on supplies for the Divine Beast.
Link got out his spear and charged an attack. When he heard Urbosa's voice he stabbed while saying, "Where is the Master Sword?" Urbosa heard the first part but vanished during the first syllable of 'Master.' Link hoped she heard him over the thunder. Link charged again and said the rest of the question really quickly.
He charged a spear strike for the last time and heard Urbosa saying, "Traditionally it was," before she vanished.
Link sighed sat down next to Scruples in the shade. "Aaaaand I'm gonna have to wait for her to recharge energy now." Scruples got up and was turning around. He seemed to be trying to say something. Link watched as the wolf pointed his nose to the shield on the ground and seemed to be holding a paw up. He made an odd growling noise. Link listened as Scruples repeated himself. Link caught on the fifth time. The growl almost sounded like the way Daruk would announce he was ready to protect Link.
Link said, "Hey, good thinking!" He picked up his gear and sought out some bokoblins. He hoped he'd be able to get ideas on where to look for his sword but if not, he was going to have to wait to hear how to get into Gerudo City. The Thunder Helm needed to be returned. He wanted to get the warp spot on Naboris activated before he returned it.
Daruk was summoned after Link chose his words carefully. A Bokoblin struck and was knocked out as Link said, "Ask Urbosa." Link avoided retaliation for a couple of minutes to let Daruk ponder the cryptic statement. He hoped Daruk and Urbosa caught on to what he was doing. Link decided enough time had passed and pulled out the shield.
Daruk, before he was cut off said, "Nowhere people have bee-." Link deflected another blow, "-she hasn't heard wh-" Link wished he got more out of Daruk. Urbosa not hearing where the sword was did confirm something at least. The Master Sword was no where people could normally be able to get to. He could rule out the Great Plateau since that place had a thorough examination by Link. Link did not think it would be in Hyrule Castle or Hyrule field. The myriad Guardians would have spotted it. Zelda wouldn't want to test how many Guardian lasers it took to break the sword. Impa had informed him that Zelda hid the sword after he and Urbosa fell in battle. Link had marked map sections with likely locations whenever he reached a tower. He'd sketched a map in his notes of places people said were well-explored to rule them out.
He hadn't been planning on raiding the Divine Beast until the Blood Moon struck that night. Blood Moons had, as far as Link knew, at least a day or two of time in between them. The sane and normal thing to do would be to take the Thunder Helm to the Gerudo and ask them for help stopping the camelbot in its tracks. Link had seen a boulder on a rock cliff with a clear line of sight to Vah Naboris. The duplex bows were going to come in handy now. Link switched to the stasis rune and counted his bomb arrows. Scruples was not going to like this. Mipha's Grace was ready.
Riju woke up bright and early with the dread feeling that there was going to be a difficult day again. Buliara told her the team hadn't found the helm in the ashes of the Yiga Hideout. People were preparing to evacuate since Naboris seemed even closer now than ever. She looked over the city towards the errant machine.
"Buliara, isn't there anything we can do to at least slow it down?"
"We were working on a long-range mechanism to attack it. It may be done before Vah Naboris gets too close."
Buliara's eyes were searching for attackers on the walls which meant Riju saw it first. There was a miniscule dot flying in the general direction of Naboris.
"Hey, Buliara, did you see that?" Buliara turned her head just in time to see the flashes of fire and smoke around the feet of the Divine Beast. With the all the smoke and sand, they didn't see the guy sliding down the back and scrabbling for a handhold. Everyone went outside that evening to see when Naboris changed direction and parked itself elsewhere. They heard a commotion at the front gate and one very annoyed guard saying, "Not you again."
An hour after that, a Hylian with a wrap skirt made from two hoods came through the door. 'She' was wearing a stealth mask and the scarf was wrapped around the torso to make a feminine-looking top. Link pulled out the Thunder Helm and handed it over to Buliara.
Notes: That is a lot of artistic license. As a heads up, reviewers have pointed out more clarity issues. I told myself I wouldn't do extensive editing until I have finished figuring out the rest of this but...
Does it count as Link from Breath of the Wild if it is the Link from the tapestry? JamesBirdsong, ChangelingRin, Valonstar, SilentN, Green Swordsman, MoonSamurai, Lleu, Reaper4425, Ann, FCL, and Akabane Kazama are people deserving of gratitude.
