We had fun with this, but there were some issues. Some things were hinted at in the details but no explanation was given for them (like the painting in the foyer, which my party found creepy but had no explanation). Biggest issue was at the end. There is a very obvious entrance with open doors and also a tree that could be climed to get up to a balcony. The storyline seems to expect the party to climb the tree to get all the lore. Party went through the doors instead and I had to work harder to figure out when and how to get the lore explained and otherwise tweak a lot of important stuff on the fly.

BTW, one of my party got rid of the first piece of coal by re-addressing it to another party member who wasn't there tonight and then taking it with them. The text didn't say what would happen if someone tried this, but it did say that only the person the coal was addressed to was affected by it, so I allowed it. I'll guess we'll see what happens with that little nugget later.
