The white suit
Magnus saw Alec from across the battle filed, he yelled at him to look out for Sebastian. but Alec couldn't hear him, Magnus' eyes widened when Sebastian's blade went though Alec, the demon/Nephilm smirked at Magnus before disappearing in the coward, the warlock gave up what he was doing, and ran over to Alec. he dropped to his knees and held the blue eyed boy to him. "Alexander look at me please." he begged. he where still breathing, Magnus used what ever power he had left trying to heal the boys wounds. he wished he hadn't been that suborn and let the boy explain, he wouldn't have gotten distracted. this was Magnus' fault and he knew it "Stay with me Alexander.." he said softly. still fighting to keep the young boy alive. but this task was impossible even for him. Magnus kept Alec alive as long as he could completely ignoring the battle that where still going on. "You where suppose to grow old. we had a future.." Magnus where so tired he hugged the boy to him. rocking him in his lap. "Alexander Lightwood, i will always love you" he said. and as Magnus's last powers fated so did Alec's life. Magnus laid down next to the fallen Nephilim. he could no longer see the light. he no longer knew how to move. he laid there waiting for the battle to take his life as well. and so it did.
he had never been so relived to realize it wasn't hell waiting for him, instead it was Alec, Alec where now dressed in a white suit instead of his black gear. "Hello Magnus" he said with a faint smile. there was no longer any runes on his body. he didn't need them. Magnus ran across the room and hugged Alec to him. "Hello my love." he whispered.
