This is where bloodshed has been a permanent view.Where swords clash,there is no room for cowards,where is the bow,there is no room for fear and hysteria.The mighty scepter of the Dark Lord will cut the air,the sword of the Blade Master will cut the enemy,the magic of the Grand Master will end all evil.This is done for one purpose alone,to save the Mighty Archangel's sword.
