Estelle was given the key to enter the Dukedom's dungeons.
In fact, the dungeons hadn't been used that much. Criminals and convicted people were taken care of in a separate place, to not further endanger the manor itself.
So, the Dukedom's dungeon was actually very neat and clean, suitable for living comfortably. It was also made this way to accommodate for the two siblings.
To avoid being seen by guards, Estelle asked her parents to vacant the space. The order was executed, and Estelle soon made her way to the dungeon.
Upon arriving, she opened the gates to the secluded room. With a metallic clang, the lock that was guarding the doors clicked open and was able to be removed.
The door itself was imbued with magic for further protection, but it recognized Estelle's authority and dispelled in a flash.
She lightly pushed the door open, peeking at the insides to spy on the scene.
With a careful glance, she found Derrick lying on top of his bed, sitting in a meditating position.
