It's been a long time since I compulsively checked for a nosleep post update but this one has me on the edge of my chair. I sure hope you get there in time to save Grace.

Do you think your house is bestowing any kind of benefit on you for feeding it? It seems like you're allowing it to feed on the evil people in the world without expecting anything in return...unlike The Crone. A house that has a penchant for innocence and rewards the one feeding it can certainly turn a good person bad.

This one hurt my heart. Poor Pamela.

This sounds incredibly dangerous. You need to contact the nearest university with a parapsychology expert, if you can find one. This is not a job to do alone. It sounds like a doorway to another plane of existence, and if you can get in then something there can surely get out. Good luck, be as safe as you can.
