The End at the Beginning

In the Prologue, the player controls an Arisen of ages past, who sought to confront the Dragon. It is the very first chapter as the player starts a New Game, although it is not listed in the Quests log. The Prologue mostly serves as a Tutorial, for the player to become familiar with combat controls and issuing orders to the Pawns.

Objective
The Arisen is destined to defy the Dragon, who terrorizes and destroys the land. With the assistance of his faithful Pawns, the Arisen has to fight his way through the Wyrm's lair before he would face the fearsome creature.

Details
The Prologue begins upon starting a New Game.

After slaying the Chimera guarding the gates, the Prologue ends with a cutscene. The player would afterward go through the Character Creation process to play the fate of his Arisen, which begins with Harbinger of Destruction.

Walkthrough
Harbinger of Destruction is the first mission in the game. In this mission you play as a young arisen(I don't know) that has to kill the dragon. It is a rather class based tutorial, that shows you the fighter. You go through a goblin, harpy, and Chimera (goatlionsnake) that all try to kill you. It is not very hard tutorial, but it shows you different types of fighters you may encounter, and strategies you can use. It ends after you kill a lion boss, or die from the same boss, and you do not fight the dragon.
