Story mode is my only option at this time, but I see you can also play "dungeon mode" which is also a single player game and "multiplayer" for your buddies to join in the action.
The Architect's Mansion will be your first mission and dungeon to explore appointed to you by Aldora. The monsters there are weak and its quite easy to kill and you will also learn the basics of the controls. At that dungeon's end you will meet Rabirius who is a legendary hero and he will talk to you about the living dead and such.
Here on the video below I meet the legendary hero Rabirius who seems to be a ghost, then after that, I meet Aldora again who will instruct on the next missions. Overall great adventure game. I am enjoying it much. ^.^
