Wow I just found the trio of guardian and prisoners memory not gonna spoil anything but that was so unexpected! :O super excited to see your next update! <3
Just since you seem open to creative suggestions I have an idea X) so maybe there's an especially dangerous prisoner in solitary confinement that you might happen upon. The guardians only check his cell once a week so depending on when you carelessly venture into his confinement you might have spent several days trapped with him before the guardians find you. Just an idea I had XD
