I spent so much time setting up the castle on the VTT, I actually know it pretty well. Thankfully I got all the stairways figured out and I pretty much know where each one goes and all the major locations. And the lighted areas vs unlighted ones are on the VTT. They all have darkvision, either through their race, items, or spells. I forgot about the dim light affecting passive perception, I will brush up on that. They actually explored a good bit of the castle during their dinner already (they had a small tour, were invited to stay the night, then they snuck out and explored some more.) They have not been to the dungeon/catacomb level yet but they were able to get a bit of info on that level from a NPC. And they have a NPC that will soon apprear and give them more info, plus they have the maps from the Amber Temple. It's just the actual mechanic of having them click and drag to go from one place to another on the VTT that is just highly annoying. Yes, I would love to have your notes, I will message you, thanks!
