I take Thsaa back to the monastery, still hardly believing the man walking by my side was the sweet little child who had evaded his parent to warn us. Even harder to believe that the masks in my arms were all I had left of my dead mother, and that my Oni pendant was covered with her blood.

"So, let me get this straight." Thsaa says as we approach the monastery through the thick forest just in front of it. "You and your brother created this place? Just using those little elements?"

"They're elemental weapons now." I tell him. "But yes, all thanks to you, I suppose." Thsaa grins wide, making him look like the child he once was. Hard to believe he's the father of two children that he named after us.

"I always assumed the elements were useless." Thsaa tells me. "I was never allowed to touch them, I'd never seen them. But to think I helped to create this place, what did you call it again?"

"Ninjago." I say quietly. "After our father and mother, both of whom are now dead." I look at the ground, determined not to cry in front of Thsaa. But it helps that we've just reached the monastery and Thsaa is now gazing up at it in awe.

"Wow, you BUILT this!" He exclaims in wonder. I look at our familiar old monastery. It doesn't really seem like a spectacular creation, but Thsaa is looking at it like it's out of this world.

Well, it is out of his world.

"Let's go in." I say to him, smiling. "I'm sure Thekallcius would-" But my words are cut off by the most horrible sound in the world. A scream. A really deep, horrible, filled with pain, scream.

"What was that!" Thsaa exclaims, gripping the knife in his belt. I create another sword out of nowhere.

"I don't know, come on!" We run forwards towards the sound.

In the weapons room, the roof has entirely fallen in and Trust is trapped under it, screaming as the heavy wood crushes his frail body.

"Trust!" I shout, and try to think of something I can create that will help him. Thsaa, however, runs forward and begins to try shift the rafters. I quickly run to help him and together, we manage to free my friend.

"Trust, what happened?" I gasp as he shuffles away from the hole in the ceiling as fast as he can.

"He did!" Trust shouts, pointing up at the hole. I raise my head to look and my mouth drops open.

Thekallcius stands on top of the roof, scowling down at us all, but that's not what I find the most surprising. It's the fact that his eyes, once again and for the first time in twenty years, are glowing purple.

"Thekallcius!" I scream at him. "What are you doing!"

"Shut up!" Thekallcius shouts, his voice with a low, sinister ring to it. He jumps down and lands on top of the debris.

"You did this?" I exclaim. "To Trust?" I'm not even angry. I'm just hurting all over.

"Why did you bring humans into this world, Mauricious!" Thekallcius shouts, not Mauri, Mauricious.

"We did it together, for a new race!" I tell him what he already knows. "We did it together-"

"No, you did it!" He shouts, grabbing a long knife from his own belt. "You brought them here, I only brought darkness! Everywhere I go I can only bring darkness, because all I can do is destroy!"

"Theke, no." I shout at him. "You don't-"

"SHUT UP!" He screams at me, whipping the knife towards my throat. I take a step back. "SHUT UP MAURICIOUS! YOU DON'T GET TO CALL ME THAT!"

"OK, OK." I say soothingly. "Just put down the knife, Thekallcius, and we can-"

"No." He snarls. "The knife never be put down, because I am the destroyer! I've done my research, there can only be good and evil in this world, Mauricious. Not both, not a mix. There is the good, in you, you modelled this realm, made it so... perfect!" He says this through gritted teeth. "And I couldn't put in what I wanted in my mind. So my only hope is to DESTROY it that way!"

"Thekallcius, what..." I'm lost for words. "No, you don't, Thekallcius. Ninjago belongs to both of us-"

"NO!" Thekallcius howls at me, and I take another big step back, away from my brother, the person who I love and Trust more than anyone else, waving knife around, pointing it at my throat. I can feel a lump in that throat, clogging it up. I can barely see because I'm blinking my eyes so much.

"Ninjago can never belong to both of us." Thekallcius snapped, taking a breath, calming down. But his eyes remained purple. "No, it is a world of good and evil, but they can never co-exist! No, good and evil are enemies, they have to be! Just like us Mauricious. I know we've been brothers for forever, but not any more. This fight has to happen, we have to fight for Ninjago..." He stops and frowns at Thsaa all of a sudden as if he hadn't noticed him before.

"Who's this and why is he here!" He demands, his knife moving to Thsaa.

"It's Thsaa, remember, from that other realm!" I hope Thsaa's name will spur a memory in my brother, happiness, a little boy. But no, Thekallcius's darkened expression slides into ugly.

"Ah yes." He mutters darkly. "I remember. The people who HATED us, Mauricious! Who tried to kill us, do you not remember?"

"No, do YOU not remember!" Thsaa scowls and whips his knife out of his belt and holds it up against Thekallcius's throat. Everyone freezes, even me. I absent-mindedly help Trust to his feet, even though he can't stand up.

"What's going on?" He mutters sleepily, there's a large bruise on his forehead.

"Don't go to sleep." I warn him. I'm not a very good medic, and we need to get out of here. But Thekallcius and Thsaa are still on the verge of a battle and I'm still not sure what's going on with my brother.

"I helped you get away, idiot!" Thsaa snarls at him, his knife still pressed to his throat. "I helped you to create Ninjago and for my crimes I got exile for ten years. And this is my reward!"

For a moment, Thekallcius looks scared. Then he laughs.

"You never used to be this feisty." He mutters, then swipes with his knife, pushing Thsaa's away. Before I know it, they're engaging in some sort of knife battle. I can see how good Thsaa is now, but Thekallcius is fighting like a madman with every ounce of passion and hatred behind his swings. I can't bear to watch them kill each other.

But how is the power of creation supposed to help anyone?

Unless.

Gently placing the barely conscious Trust on the floor, I level my hands and eye the floor, the stone floor that me and Thekallcius laid together. But if I can change the way that floor was laid, maybe change it, create something that wasn't there before...

It works. I see cracks appear in a square shape, and a lever appearing at my left. I just have to wait until the right moment...

Now. I yank the lever, hoping desperately that it will work. It does and the floor disappears under my brother's feet. He gasps and falls through, five meters down or so. Thsaa stumbles backwards, almost dropping his knife.

"Come on!" I shout at him. "Help me!" Thsaa is still confused, I can tell, but he slides an arm under Trust's shoulder and helps me carry him out.

"Where are we taking him?" Thsaa asks.

"A doctor in the village." I tell him, as we drag Trust out the room. I can't tell if he's conscious or not. "Trust? Trust, stay awake, you hear me?" He gives a low moan but that's all I get as a response.

"What WAS that?" Thsaa asks as we limp out of the monastery.

"I don't know."

"How long had Thekallcius been like this." I try to think back to when his curious behaviour started.

"I don't know."

"What happens now?" I look into his earnest eyes and see the same scared child who discovered us by the waterfall all those years ago. Back when things were alright.

"I don't know."
