Inside a house on some long forgotten island

About this image

Who lived here? What's the story behind these rooms? Why here? Why in this abandoned place, why on this forsaked island?

No ENB is used; This might be part of a Story/Horror-Mod I'm making, but I can't say for sure that I'll finish it, yet. Would be very happy for some Feedback!

Stroti's Manor Ressource is used, aswell as some Clutter Items made by Blary.
