Ace and others returned to the Thief's Space instead of the Thief's House Space because of the two prisoners. After all, the Thief's Space can suppress their cultivation base, and he didn't want to reveal the Thief's House space yet.
Since Zaria had captured Eleanor and Ravencrown, Ace knew the Nightfall Ravenhood won't abandon them easily, especially the Ravencrown, who seemed to have the deciding power in the Ravenhood.
Furthermore, he wanted to learn the secrets of the Nightfall Ravenhood and what they were after in the Great Crown Domain. Lastly, Ravencrown was a Glittering Amber Fate Point; he needed to figure out why.
After everyone left, the Thief's Space was serene, but when Eva, Alina, and Zaria entered, it became boisterous. It was Zaria's first time seeing the Thief's Space, and when she saw mountains of treasures scattered around, she was astounded, especially by the countless space treasures.
