Yes, a bit dark. Patients are experimented on with drugs and tend to disappear. I think we already let a patient called Simon disappear, they told our character he had gone home, but in reality he died. And Benjamin knows, because he saw his ghost when he came to say goodbye. 

The psychiatrist is leading the experiments, but to the world looks like a caring woman who has the best intentions at heart.

And personal drama too. For Benjamin I have at least one claustrophobic attack planned. And some questioning of his sanity, because while he really can see ghosts (which most people can't), he'll have moments of doubt because everyone keeps telling him he imagines these things and he'll start to believe it.

So any kind of personal struggle and drama you can think of for Artemis is welcome.
