From the introduction:
This game is a tragedy. It is supposed to be so from start to finish. The tale the game will try to portray will recount a group of warlocks, demon-binders who use their powers in order to defend The City from the marauding armies. They will fail in doing so, a most spectacular failure as there is a traitor among them, but they will sure try to succeed. This is the story, the narrative, of how The City disappeared, how it was forgotten till no one, except, perhaps, Death itself, was left to tell its past glories, to tell of its tragic end.
