The next day, I tried desperately to convince Astrid to stay on Berk.
“You have to stay here!” I said, my hands on her shoulders.
“No way!” she replied, shaking them off. “We found this place together, so we're fighting this masked maniac together.”
“You saw what that guy did to those villagers. He's a brutal murderer that doesn't care for life. If you get hurt, I'll never forgive myself!”
“Hiccup, I was born a warrior!” Astrid fought back. “I can deal with this.”
I smirked. “Even you gagged at the sight of those bodies.”
She groaned, knowing I'd won. “Fine, I'll stay here. But if I think you're gone for too long, then I'm coming to get you!”
I smiled, reassured that she'd be safe. “Thank you.”
Later on that day, I watched from a cliff as the man with the mask grabbed the villager Astrid and I had spoken to by the neck and lifted him clean off the ground.
“WHERE IS HE?!” I could hear him yelling. “WHERE IS THE CHIEF?!”
At first I had decided to wait a bit before making my appearance, but I saw the masked man take a dagger from his belt and get ready to stab the villager in the stomach, and this made me change my mind.
A chief protects his people.
“I'm here!” I yelled. I climbed on to Toothless' back and flew down to where they were standing, surrounded by other Vikings who were wearing simpler versions of the man's iron mask. These men immediately started advancing towards me, gripping their blood-stained axes. Not at all intimidated, I grabbed Inferno and sent a ring of fire burning all around me. Because of the already-burnt grass this ring of fire didn't burn for long, but it burnt long enough to surprise them.
I turned to the masked man. “Now you have me, let him go.” I gestured to the villager he was still holding by the skin of his neck.
To my surprise, instead of letting the villager go, he thrust his dagger deep into the poor man's stomach, crashing through his ribcage as he did so. I watched in horror as he proceeded to stab the villager once in the middle of face and then throw the still-alive body on the ground.
“You didn't need to do that!” I shouted angrily. The worse thing was the villager was still alive, despite the serious wounds, meaning he was suffering where he lay. I took my knife from my sleeve pocket and made a quick and clean cut on the villager's neck to put him out of his misery.
“I always need to kill,” growled the masked man, wiping his bloody dagger on his thick leather trousers and then slipping it back into his belt. “Especially the people that aren't important.” He kicked the body at his feet, making it roll over and hide its bloodied face.
“But YOU,” continued the man. “YOU I will take ALIVE!”
Before I could react, I felt a sharp pain in my neck as a needle was thrust into it from behind me, sending me into unconsciousness.
When I awoke, I saw that I was in a dark room with walls made of stone. I was surprised to realise that it wasn't that cold. Once my eyes had swam back into focus, I looked round and not only noticed a fire was lit in the corner of the room, but I also noticed that I was chained securely to a chair.
“Sorry if the accommodation isn't quite what you're used to, Chief...” came a voice from behind me. I couldn't turn round to see but I knew that it was the masked man.
“I did light a fire for you, though,” the man continued. He walked slowly towards the fire and picked up a metal rod from the side of it. He slowly put it inside the burning flames, watching as it turned from grey to red to blue with heat.
Once it was blue, he walked with the same slow pace as before towards me.
“As for medication,” he said. “This is to insure you don't catch your death of cold.”
I could only scream as his touched my right cheek with the burning rod. He left it there for what seemed like centuries and then finally threw the rod on the ground. I couldn't see but I was sure that it had left a mark that would never leave.
“Who are you?” I practically whispered, half of my face hurting like hell.
“You don't recognise me?” asked the man. “Then again, I have changed, haven't I? I was never this brutal, and this is actually the first time I've ever been in command of my own tribe. I'm quite new to the job, but I think I'm doing well, wouldn't you say?”
“Tell me who you are!” I said furiously.
“Give me a moment to finish my speech,” said the masked man calmly. “I was up to the bit of where I had changed. And I shall continue to say that you have not.” He laughed. “Still as small and as weak as you always were, Hiccup. You might think you've grown, but there's still the puny little Viking – if we can even call it a Viking – inside you.” He laughed again as he saw that what he was saying struck me hard, like verbal arrows being shot without end. “A runt like yourself has managed to become the Chief of Berk, Odin only knows how, and it doesn't take a genius to know that you are WEAK.”
I tried desperately to block out what he was saying, but I couldn't. “A strong chief wouldn't have given himself up like that. A strong chief would be back on Berk, getting reinforcements, by now. But no, seen as you are WEAK you've decided to give yourself up and let yourself be chained. Because of you, the rest of those stupid villagers will be strung up like the first ones. How does that make you feel?”
Determined to not let him win, I put on a brave face and asked again: “Who are you?”
Now that his speech was finished, the man removed his mask to reveal a face I barely recognised, but still knew from years ago. His eyes glinted with power and fury and this almost gave him a completely different appearance.
“How is that possible?” I wondered out loud.
“While you were fighting Dagur with Alvin, no one noticed ME on the sidelines. No one ever notices me. I crept away like a shadow and made sure that no one knew.” He smiled. “As you've already found out, I've inherited Alvin's taste for blood and Dagur's taste for madness... That's what you get from working alongside two of Berk's enemies.”
He leaned forward and looked me straight in the eye. “What's it like to see your old friend Savage again?”
I bet you weren't expecting the villain to be Savage, right? 
At first I was going to use Drago as a villain, seen as we never actually see him die or get captured at the end of HTTYD 2, but while watching Cast Out pt 2 of Dragons: Defenders of Berk, I noticed that we never see Savage get captured either. And that got me thinking: what if he came back, with a whole new personality: the mix of Alvin and Dagur? I personally would be pretty intimidated by this XD
I hope you all liked this plot twist!
