Dark School

Your grandfather is dead.
You travel overseas to attend his funeral and discover that you are the apparent heir to his estate and property: a mansion with a vast forest littered with ruins and grottos.
Inside his diary you discover his involvement with occult experiments and realize the domain he left you is not an inheritance at all - it's a proving ground.
Leave behind the world you were born into and carry on his noble work. Become a worthy heir not only to his vast fortune, but to The Great Work, and restore eminence to your family name.
A great destiny awaits you; or perhaps, an untimely destruction. Follow your fate and find your path.
Once you enter, you can never go back.
You Must Choose.
