“ MEN, Remember that what you do is not for only you, ” General Ephal ’ s speech began to fade as Alek began to think about other things. He knew, just like all the battles before, we were supposed to open up the enemy ’ s ranks so that the real heroes could take on Lord Arthgon and send him back to the 5th realm. Alek stood among the ranks of his fellow soldiers. He wondered if the others had thoughts like his. Alek thought back to the dream he had a few months ago when he saw himself, on a throne made of solid gold and encrusted with gems and stones. He knew that this could never happen, but he liked the idea that it could. 
 
 “ Now, ” Ephal ’ s speech began to come back into Alek ’ s ears, “ We will march on the keep, and remember to take them with you. CHARGE! ” the men began to charge the keep, swords hit swords, metal on metal, blood was everywhere, that ’ s when Arthgon stepped out of his tent. He lifted his staff and sent fireballs into the ranks of both his men and ours. Alek barely dodged out of the way as a fireball flew by his head. Then Sir Reginald appeared. A six foot tall paladin who was supposed to be called upon by god to stop Arthgon. Reginald drew his sword and charged Arthgon. The fight was stupendous, almost all the fighting stopped to watch these two titans duke it out. 
 
 Alek, having no one left to fight near him began to move closer to the fight, hoping to learn something from the two titans that he might be able to use to his advantage. Maybe a new fighting style that would allow him to join some adventures. Maybe he could write a book about the epic final battle between these two that would bring an end to this brutal war. Then something bad happened. Reginald lost his footing and was put on his back. Alek panicked and grabbed a bow lying on the ground and notched an arrow. He fired. It hit. The arrow hit Arthgon directly in the throat. He fell to the ground clutching his throat and died. 
 Reginald stood up and made eye contact with Alek. Alek stood there amazed at what he was able to do just then. He wasn ’ t expecting to kill Arthgon in one shot. He had thought it would simply allow Sir Reginald time to get to his feet and continue the attack. Alek saw Reginald and the look of utter disbelief on each of their faces was the same. Sir Reginald fell to his knees and began to weep. He was raised all his life to believe that he was the one who would bring down Arthgon, and now, some soldier had done it. Alek stood there, the entire battlefield was silent, all eyes either directed at Alek or Reginald. Then one soldier began to cheer. 
 
 “ Alek, Alek, Alek ” the entire army began to cheer and chant his name. He was lifted by the soldiers and carried around while they cheered. After the celebration was over Ephal called Alek into the captain ’ s tent. “ Well soldier, you ’ ve done a great thing today. ” The General ’ s words had a sense of pride behind them; Alek thought he wasn ’ t expecting today ’ s events either. “ You will be herald as a hero, money, power, glory, woman, drink, and anything you want will become available to you. However, you will be expected to uphold the appearance and behavior of a hero. It is vital that the people see you as chosen by god to be king in Reginald ’ s steed, we will have to disgrace him of course, we will have to come up with some reason as to why god abandoned him and chose you. So are you ready for your time to shine? ” 
 
 Alek thought about this question for a second and remembered his dream. “ Yes ”
