It’s good practice!
That’s awesome. I love the attention to detail for each party member (which is exactly what we would expect from you). I bet there’s a story behind the dragon skull and the piano. I wish I still had my mansion maps from that epic game (it was about ten years ago).
The piano is actually there because we needed a ballroom to entertain some NPCs for a political summit. Several of the servants in the mansion were skilled in instrument use, so we made a small area for performers.
The Dragon Skull is in the sand of a fighting/training pit for the party’s fighter. She basically took out a red dragon single-handedly during one of our adventures, and it’s a replica of that dragon’s skull that we couldn’t take away as a trophy because the dungeon collapsed.
