Lith drank his tea and went over to snuggle closer to Lucy. He saw Ren in the corner of the room and wasn't comfortable with him here when he was getting intimate with his big sister. He therefore put Ren in his spatial ring.
The spatial ring was very big. It had an area of 10,000 km² and could be increased as Lith's magical rank increases. It could accommodate living beings inside with no problem. It was almost like a mini world.
Such a spatial ring was very difficult to make and needed atleast the help of a few King ranks who were proficient in space and time elements. It was made by Lilith and it was the best spatial ring in the world. Only three people had such rings. Lilith, Lith and Lucy.
Lith made accomodation in his spatial ring and put Ren in there with some toys for him to play. He put enough food for him inside and gave him toys on which he could attack and play with. His pet was a male and he didn't like it when he thought that he would watch them.
