An event idea regarding that. But maybe you could bring Linda to the broken Iron Maiden and have her fix it up for you. And then it could be added as a new addition to your dungeon. Considering I’m pretty sure losing to it leads to a bad end, which are usually pretty kinky. Though Cassie would probably have some colorful things to say to the player for bringing it into the base at first. Especially when you consider she might have been subjected to it herself at some point in her past. Which could lead to a little bit of convincing that it isn’t so bad when in the right hands ie the player and the inviteable NPCs. Also maybe something extra to the dungeon itself is that you can have NPCs dom other NPCs. I mean, you CAN have more than one character in the dungeon at a time.
