*They bring suffering on a scale you can not imagine. You have to stop them from reaching the Eternity Gate because if just one of them makes it to your world all will be lost. * 
 Yamagi's final words. Sage of the West.

 Tasha could feel herself growing weaker with every step. One if the guardians had caught her with a single slash and now every part of this final trip was agony. Behind her there lay the path that had brought her this far. 
 
 Up ahead was what remained of it. It looked longer than ever. 
 
 The clouds were swirling as she descended into the pit. Years ago this had been open to the elements, before the sages realised what was on the other side. Before they had opened the gate. 
 
 The war had ravaged the world, and at the end of it, after all the fires burned out, the survivors had gathered where it all began. They raised a city as both a memorial to the fallen and as a shrine to celebrate the hope they had earned. 
 
 Tasha fell another step, steadying herself with one shaking hand. Wincing in pain she pushed on. 
 
 Rath was somewhere ahead. Hopefully he had been weakened as well, the guardians being indiscriminate with their choice of targets. 
 
 Not much further to go. 
 
 The world was gathering. Storm clouds loomed, lightning striking. Even though most of the people slept the elements themselves stop vigil over the end. 
 
 A dagger, one of a pair, clattered from Tasha's grip. Forgotten forever, it would lie unclaimed until it gathered rust. 
 
 She pressed downwards, the stone stairs growing rougher with every passing turn of the spiral. No man had ever meant to step foot here again. But now Rath forged ahead and Tasha, the embodiment of desperation, have chase. Blood marked their dance downward. 
 
 How long she walked, Tasha could n't tell. By the time she got within sight of the Gate itself she could only be certain that it had been too long. Underground now, she could feel the cold air on her face. 
 
 Far above the storm broke. Rain lashed the city. 
 
 `` Rath!'' 
 
 He was standing on the dias in front of the gate. One arm hung uselessly at his side, the other raised, that fist forming an arcane symbol. The magic hummed in the air. 
 
 He did n't turn. He was too focused on what he was doing. 
 
 `` Do n't do this!'' She shouted, lurching forward. He was too far away. `` Things will be better! You have to-'' 
 
 `` I have to do no such thing! You betrayed them all!'' It was n't Rath speaking. It was fury itself. `` And for what?'' 
 
 `` For a better world!'' Tasha screamed. The hum was building to a crescendo. 
 
 `` For your own selfish ends! Power, Tash. That's why you did it.'' 
 
 `` No!'' Tasha moved faster, pushing herself beyond her body's limits. The wound she had suffered at the hands of the guardians tore open, but she never felt the pain. Too much had hurt her in the past. 
 
 `` The gate must not be opened! They will make us all suffer. You have to realise that!'' 
 
 Tasha drew her remaining dagger and almost fell. Rath turned his attention back to the gate. 
 
 `` Please. Please stop. Please.'' 
 
 `` Begging. How unbecoming of you Tash. You had always been so strong. But I'm through listening. I'm going to finish it for good.'' 
 
 Trembling hands made it difficult to aim, but she threw the dagger anyway. Rath's back was turned, his attention focused completely on the gate. 
 
 It was an easy target. 
 
 He called out in pain, falling away, the magic overwhelming him. It escaped into the air. 
 
 Rath's crumpled form hit the cobblestone floor. 
 
 Tasha pulled herself toward him, tears streaming down her face. The gate was humming now, the magic arcing in every direction. 
 
 `` I do n't want to rule the world. But you have to see, you must understand, that the human race has to suffer. It has to be made accountable for what it has done,'' Tasha muttered as she turned her face to the gate. `` They are the only ones who can hurt us as much as we deserve.'' 
 
 Rath was still alive, trying his best to get back to the gate. If only he could finish sealing it... 
 
 But he felt a hand close on his leg. Tasha's. 
 
 `` You and I were the only ones who could stop this from happening!'' He kicked her lose. `` We were the only ones.'' 
 
 `` We were also the only ones who could start what had to be started. But do n't worry, Rath. They will worship me as a god when we take this world. And I will give them you.'' 
 
 Rath could see the gate cracking open and, as the flood of darkness spilled over them, he felt despair.
