As they approached the two large gates of black iron, embedded in bone like structures and skulls. Persephone noticed something strange on the other side of the glass wall on her left.
She stopped walking and squint her eyes, trying to adjust her vision. She could have sworn she had seen some movement on the other side, was it Hades' pets that she kept hearing about? She wondered what they were exactly.
She turned to look at Hades who had paused at the gates, she figured he wouldn't mind if she took a closer look.
Persephone walked slowly towards the glass wall, for some reason feeling a little nervous about it. She bent forward to get a better view, and was surprised to see what looked like an entire ecosystem on the other side.
There were dark treelike structures, a creek of flowing murky water, strange blue and purple plants, something that looked like grass, and a number of tiny things flying around that Persephone concluded were insects.
