The cannon doesn't so much have a barrel, just a more intensely glowing bit at the end.

They seem to be doing some accumulated damage, though. Windblight Ganon gives another shriek of pain before changing and speeding up his attacks. He also deploys a small array of drones that fire showers of blue light at both opponents.

"Good, you're making progress! Much more of this and he'll reach his breaking point."

Alice uses more bobbles to shield them and keeps firing. Dodging as she goes. "Holding up alright?"

"Huff. He's tough and I'm doing most of the dodging but it's working!"

Back to the fight.

It's more of the same from this point.

Eventually, Windblight Ganon starts bleeding massive gouts of black blood. A few more lasers and cuts into it, and it explodes in a blast of corrupted-looking purple light.

When Link's ears stop ringing, Revali is almost shouting at her, "Are you alright, Link?!"

Alice jogs over unaffected by the noise. "I think the noise was just a bit much for her. The magic making her tougher seems to be intact and it looks like she still has a healthy margin before she'd be seriously hurt."

"Yeah - ow - I think I'm okay. Just. Ow. That was an explosion. Why did he explode?"

"The magic destabilized when his form got too damaged. Some of it went elsewhere but a lot of it just came out in a physical effect. It's a bit like what the Guardians do. I should have expected that, I guess we know for next time though."

"...Oooh that's right you two have magic vision or something. What else could you tell about him? Know your enemy!"

"Alright, so the first thing to note is that there's a vague something in all of the various creatures of ganon we've encountered, including the Guardians. Windblight ganon had more of that thing and more variations of that thing. There was more of an intelligence behind it than the various smaller enemies we've fought. In some ways there were similarities to what we saw when you were communing with Hylia. That had a different sort of pattern to it but the types of magic had a lot in common. The thing where he'd move from place to place had a lot of similarity to the way you teleport. It wasn't using the actual teleportation part of your teleport but the part that prepares you for it. The way he was manipulating the air for those tornados was pure force application. I'm pretty sure that he could have made more tornados if he wanted to but maybe he abandoned the tactic after seeing how easy it was to disrupt. Those drones that were firing towards the end had a lot in common with him but they were dependent on him to work, I don't think we'd ever see something like that far away from one of his bodies like this one."

"...Hmm. I'm not sure what to make of that, to be honest. It's bad news that he's kinda similar to Hylia, just confirms he's got godlike power. But anyway... We did it! Vah Medoh is free! Right, Revali?"

"Not quite yet. You have to activate the final terminal, then I can take back control. I'll prepare for the shot I've waited more than a lifetime for. When you're ready to face Ganon, I'll give you a perfect shot from the Divine Beast's main cannon, aimed by the best Rito warrior from a couple generations ago."

Link... Has another complicated face on now.

Alice notes the look on her face but decides not to bring it up. "Thank you, your help will definitely be appreciated."

"And don't hang up on the fact that I'm dead. There's nothing you could have done, Link. The Calamity took us all by surprise."

She takes a deep breath. "You sure you don't want company up here? I could stay, catch up..."

"To be perfectly honest, there's not much to catch up on... And you need to keep moving forward, not get stuck in the past. But perhaps I'd like to meet that warrior who helped you board. I think he was injured, if only slightly."

"I'll tell him..." Link sighs. "Well, now I'm off to find the other three Divine Beasts I guess. Thanks for all the help, Revali."

"It was good to meet you Revali, I'm sure we'll all see each other again."

"Perhaps we will, once Ganon is finally gone. Oh, one last thing..."

A small, green orb, a lot like the spirit orbs, rushes out of Revali and at Link. It gets absorbed into her magic. "You always seemed jealous of my gale-updraft skill. So, take it as a gift. Use Revali's Gale well."

And then the ghost of Revali walks into the control terminal. The great bird starts shifting its flight.

"Uh, we should probably go now I don't want to fall off-"

Alice nods, "Alright, do you want to use your Sheikah teleport? or should I put us somewhere?"

"Either one. Just..." The great machine begins to bank. "Meet me by the stable!" And she disappears into the blue streamers of Sheikah teleportation.

Alice is waiting at the stable when Link arrives.

Link glides in soon after. "That was a perfectly acceptable adventure! Now we get to watch Vah Medoh glide in and land. Impressive sight, something that big moving around like that."

"It is, Van Medoh is really quite large by any standard. I'm impressed that it's able to land."

The giant bird has equally giant talons, currently braced downward as it descends towards the massive spired peak above Rito Village. "I'd be worried about the village... But I'm sure Revali knows what he's doing."

"I expect so, presumably he has a plan, hopefully he isn't working off of out of date information."

The Divine Beast lands on the wide spire at the peak of the village with thunderous noise. Shards of rock fall... But the peak holds. It stands with its wings splayed wide, the 'head' pointed forward.

Its nose now pointed toward the dark castle in the distance, a visible beam of red light emerges from it, aimed at the castle.

"You have got to be impressed by something so big. And that red beam, it's like a Guardian taking sight. We're in for a light-show when it's time to fight Ganon."

"I expect so. Depending on how long it takes before we're ready the follow-up teams might be on site. I'd be interested in seeing how resilient this Ganon is to heavy weaponry."
