Ancient Evil: The Guessing Game

Before  your grandfather passed away, he left you a key to his attic. He begged you to "uncover the truth", whatever that could have meant... 

And that's how you found it - an ancient-looking paper with weird symbols on it. Something happend to you when you touched it - it was like a burst of infinite energy rushing towards you.

 A call for help? A curse? Or a secret too ancient to be remembered by anyone?

Whatever that was, it now must be uncovered... No matter the cost.
