Introduction: The world changed. In 2075 dungeons appeared, massive structures towering outside of every major city. Spirits and monsters, quests and items, skills and elements, all were ripe for taking. Brave humans stepped forward, guilds formed  and powers rose. They all had one goal, to reach level 100. Only by doing so could true immortality be achieved.The dungeons were not so easily conquered. Fifty years later humanity had ground to a halt. They made it to the sixtieth floor but could go no further. Now 150 more years have passed, the year is 2275, and they haven't made it one floor further. With no way forward, humans become restless. Their eyes turn once again on each other. Apolleon, an ancient and evil spirit rises up. He promises a way forward but only if he can rule all the earth.  The Eastern Confederation has sworn their allegiance, the Western Alliance gathers strength, and Apolleon sets his sights on Europe.It is at this moment that Kyrios, the God of all spirits, steps forward. He resurrects a young man and gives him a new name, Jason MacGregor. Endowed with the power of heaven, he sets his sights on the 100th floor. He does not walk alone but is joined by the beautiful young branch guild leader of the Fortress guild. Only together can they scale the dungeons, curb the tides of war, and show humanity the true way forward....
