I took out all questionable magic items and potions used for interrogation, including [Believing Pill] and [Truth Potion]. I also added [Confusion Potion] and [Drunk Potion] to make her spill the bean that she hid deep within her consciousness.
To do that, I also had [Nightmare's Lamp] I used to interrogate the infiltrating assassin in the Royal Academy back then just in case I needed it. When I thought about it again, they probably were just Alexander Bluerose's guard or entourage.
This cell magic item worked like Beatrice's <Charm> or <Mind Control>. It put the person affected in a long-lasting dream that they were unable to escape.
What kind of dream they had, I wonder. It must be because they wanted to stay in the dream that they didn't even register that it wasn't real.
"Poor people," I muttered as I fed the various potions into the cultist's mouth. I also used <Heal>, <Cure>, and <Lift Curse> to try to stop her bleeding, but it was useless.
