When Midna and Link arrive in Vexona's room, Link immediately recognised Ilia, trapped in a cage to the back of the room. Link waved at Ilia, who waved back, then Vexona appeared in front of them. It was only then that Link and Midna realised how tall Vexona was. Midna was just over six feet tall, with Ganondorf at just over nine feet, but Midna is sure that Vexona was at least two Ganondorf's tall. Link growled, very like he did in his Wolf form, then said "Let Ilia go Vexona". At this Vexona laughed harshly, then said "I'll tell you what. There are two keys behind me. One opens to lock to Ilia's prison, the other opens the door behind me, which will take you to a special room that will teleport you to the entrance. But you can only obtain them, if you kill me" He then put his head up, and released a huge cloud of poisonous gas. The gas would normally have left Link and Midna with Poison, but with their new items, they were unaffected. Vexona smiled, then said "Well then I'll just have to use my power to kill both of you. And Zelda when she gets here" Link drew his sword, and the battle began.
Immediately Vexona fired a huge fist at Link and Midna, with both of them dodging it easily. Link swung with his sword, but it bounced off Vexona's arm. Shocked, Link said "What the? How did my Master Sword just bounce of him?" Vexona laughed, then said "My armour makes all sword attacks useless, even your Master Sword doesn't affect me" Link was shocked, this was going to be a lot harder than he first thought. Midna yelled "Link, what about your bow? Or your Hookshot? You could use those to damage him". Link nodded, then had to duck to avoid another large hand swing. Midna started firing magical bolts at Vexona, but found that she didn't do much damage to him. Vexona swung around and Midna had to put her hands up in front of her, and braced for impact. The combined effects reduced the damage she took to 2 hearts, lowering her hearts to thirteen. Link fired his Hookshot, and climbed up Vexona, slamming his Sword into Vexona's back. Vexona slammed against the wall, and Link barely managed to brace, but he still lost ten hearts, dropping his hearts to fifteen. Link fell to the ground, and Vexona turned around to go for Midna. Link fired off a Fire Arrow, but it did so little damage that Vexona didn't feel it. Midna fired off several pulses, but they did only a little damage. Vexona then slammed his fist into the ground exactly where Midna was, however, Midna managed to avoid it, although the shock wave did four hearts of damage to Midna, lowering her hearts to nine. Link pulled Midna into a corner, and although Vexona swung another huge fist at them, his hand was so big that it got caught between the closing corners of two walls.
"Link, what the hell are we going to do?" Midna asked. Link replied with "This guy has got to have a weak point. We've done hardly any damage to this guy". Midna tested how much damage they had done, and was shocked to see that they had only done eight hearts of damage, and it was even worse because Vexona had a hundred hearts of health. Vexona swung another fist, this time running the edge of his fist against the wall, and Midna and Link had to run away to avoid. Ilia was watching with sheer terror in her eyes. She said quietly "Link, Midna, you're not strong enough. I'm fine, don't worry about me" but Link, having been forced to go near the bars, said to Ilia "I'm not leaving until I know you're OK. And while Vexona's here, you're not safe" Link saw Vexona turn around, probably ready to swing another fist at him. He pushed Ilia back, then leapt away from his fist, although he was caught by the edge of the fist, also knocking Ilia's cage to the ground, the force of the impact having detached the chain, and the second force of the impact with the ground broke Ilia free from the cage, but also leaving her seriously injured.
"ILIA!" Link and Midna yelled at the same time, and they ran over to check on her. Vexona saw this coming, and, grasping both of his hands together, said "Now I can kill all three of you at the same time" and he then swung his clasped hands down at them. Link closed his eyes, shielding Ilia with his body, but the fist never pounded them into the ground. Instead, Midna had created a huge force of magic to hold Vexona back. Shocked, Link said "Midna" Midna, struggling with the force of the attack, said "Link, get Ilia out of here. I'll stop him" Link shook his head, and said "Just push him away, I can't take Ilia anywhere. But we have to take him out quickly and get the key, or we may lose her" Midna used every ounce of her energy to push Vexona into the Poison Pit. Vexona managed to avoid falling into the abyss by grabbing one his hands on the edge of the pit. Link, noticing this, gently laid Ilia on the ground, ran over and used his Hookshot to shoot the fingers' grip on the ground. Vexona fell, and appeared to be dead.
"Well that tells us one thing, we need to find a way to break whatever the armour Vexona was wearing, or else we won't defeat the other commanders" Link said as he ran back to Ilia, where Midna was already casting a strange spell. Noticing the puzzled look on Link's face, Midna said "I'm putting her in stasis. We can get Ilia back to Zelda. Don't worry, she'll be OK" Link nodded, then saw a key lying a short distance away. He ran over, picked it up, and jammed it in the lock of the door to the final room. It clicked. Link opened it, and Midna, after picking up Ilia, followed.
When they entered the room, Midna immediately recognised the writing all over the walls of the room. She floated over to look, and realised that it was the language of the Twili. This shocked her, but she was even more shocked when she found out just what Vexona was, and how to take him down.
"Hey Link, get a look at this" Midna said. Link didn't listen initially; his attention had been drawn by a strange artefact. Picking it up, he heard Midna call his name a second time. He walked over to Midna, then asked "What is it?" Midna replied with "It's an ancient legend about the three dark monsters created by my ancestors" Link looked at Midna, then his artefact, then started reading.
"Using the power of the Fused Shadow, they generated three extremely powerful creatures. Vexona, the demon of Poison, Carliko, the demon of Magic and Flaroko, the demon of Fire. They used these demons to wreak havoc across the land of the Sacred Realm. The sages had to use almost all of their power to seal the three demons. Without the power of the three demons, the Interlopers power were diminished, and they were stopped. As a punishment, the Golden Goddesses sealed them into the twilight realm and broke up the Fused Shadows into the four separate shards. Zant broke the barriers, but were unable to revive the demons. However, he marked them with a spell that allowed the lord in the Twilight Realm to break the seals and unleash them, also managing to control them. The only way to destroy them is to find the relic of the shadows. Only when these demons have had their heart counter reduced to zero can the relic be used to destroy them.
The moment Link finished reading this, he re-read the last few lines, and realized that these lines were much fresher than the lines above. Turning to Midna, he said "Look at this, have you noticed that these bottom lines are much clearer than the top lines?" Midna looked at the lines of text, and sure enough, the bottom few lines were different from the top lines.
"Wow, who could have put this here?" Midna asked. Link then looked down further, and saw that there were a series of notes etched into the wall. Link was just about to play the song when Vexona climbed himself up, although he had lost his armour and half of his health, leaving him with about 45 hearts, he was angrier than ever.
"HOW DARE YOU DESTROY MY ARMOUR, NOW YOU ALL WILL DIE" Vexona yelled. Link said to Midna "Distract him, you just need to distract him for about 10-15 seconds, until I play the song. I don't know what to do, I think that is the only way that we're going to defeat Vexona" Midna nodded, and charged at Vexona, who immediately swung his massive fists at Midna, which she fairly easily avoided. Link got out his Ocarina of Time, and played the song. At the moment Link finished playing the song, he felt a major power surge flow through his sword. He pulled it out of its scabbard (The item that holds a sword) and saw it glowing. Midna saw it, and yelled "Just stab it into him, let's see how much damage it does" Link nodded, but decided on a better idea. He started charging up, using up a large amount of magic, combining the new power he had just obtained, along with the magic power he already had, and did a jump-and-spin combo attack into Vexona, hitting Vexona five times in the back, dealing six hearts of damage with each hit, dealing a total of thirty hearts damage. Vexona turned around, swinging his massive fist at Link, which he countered with his shield. Midna then got over to the damaged sections of Vexona's back as he closed in on Link, and fired off her electrical attack into the scars, leaving Vexona with one heart, crippled by the pain.
"No, no, how could I lose?" Vexona asked. Link got up, raised his sword, said "The magical tune I found in the back room, I used it to inflict damage. Now, DIE!" and he stabbed the sword into Vexona's head, killing him.
"Well done" Midna said. Vexona's body decomposed and disappeared, and it was then that Link and Midna realised that the place was about to fall apart. Link grabbed Ilia, and both he and Midna ran towards the exit, and managed to narrowly get out before the place fell apart. As they got out, they heard a "LINK! MIDNA! You're OK, I heard that you two had gone to the temple" and they saw Zelda running towards them. And she hugged Midna. She then turned to Link and said "Let's get Ilia to the hospital, I'll hug you afterwards" Link nodded, and they headed back towards Ordon Village.
Midna had to keep the stasis spell on Ilia the entire way back, which took no time compared to how long it took them to get to the temple, and Zelda sent a message to the doctors and nurses in the castle to head to Ordon Village A.S.A.P. to try and save Ilia. By the time Link, Zelda and Midna had returned with the in-stasis Ilia the best doctors were already waiting for them.
"Is Ilia already in an induced coma?" one of the doctors asked Midna once Link had laid the critically injured Ilia on the bed. Midna nodded, and the doctors immediately got to work. Both Zelda and Midna held Link's hands, knowing how hard it must be for Link to handle the possible death of his childhood friend. Finally, after almost five minutes, they were forced to leave by the doctors. They headed back to Link's house, where Auru was waiting for them.
"Link, if you need anything I'm here for you, along with Zelda and Midna, alright?" Auru asked. Link nodded, and said "Thanks Auru. I'm just very worried about Ilia, that she, won't, make it" his voice quivered and broke, and Link broke down, forcing Midna and Zelda to rush and console him.
It took ages for Midna, Zelda and Auru to calm Link down. Just as they did, a doctor came in. Link immediately sprang up and ran to him and asked "Is Ilia OK?" The doctor faced Midna, then said "Whatever you did, saved Ilia. We're transferring Ilia to the Main Hospital now, it's going to be a long road, but Ilia's going to be OK. We can't have any visitors for the next day or two, and I will keep you three in contact" Link, Zelda and Midna nodded. The doctor then turned to face Link and said "I know how much you worry about her. But we need you to focus on keeping Hyrle safe and returning Midna to the Twilight Realm" he then turned to face Midna and asked "How's your ankle coming along?" to which Midna replied with "Getting better. Thanks to my healing abilities, I can recover within a few weeks" the doctor nodded, then departed. Link breathed a sigh of relief, then said "We had better rest and recover. Who knows when the next attack will come" Zelda and Midna nodded, and they headed to separate rooms.
Meanwhile in the Shadow Temple in the Twilight Realm:
"Vexona has failed. I had no idea that was even there, but how Midna and Zelda gain the power Link has, I'm confident they won't. My other, demons, can now come in and take Hyrle, claim Midna, and kill everyone" the lord said. A Fire-Demon then appeared.
"You called?" the demon asked. The "lord" nodded and said "Ah, Flaroko, good. Vexona has failed, Link has gained a piece of the Goddess Seal. Your assignment is to send your armies in, find and capture Midna, and kill everyone" Flaroko grinned, cut the communication, then roared.
A/N: So, the next demon has been revealed. With Link's new power, can he possibly have what it will take to defeat the Demons, and get Midna home? Find out in the next chapter of Legend of Zelda: Revelations of the Twilight Realm.
