After putting the Dreamer into its new home, the group dumped the Screaming Coffin into its Containment Unit on the second floor.
Wyntor had also told everyone about how he planned on dividing the Specters.
Nearly every floor would be dedicated to a different kind of Specter.
The second floor was dedicated to Possession Specters, and it had the Screaming Coffin and the Dung Heap.
The Dung Heap wasn't really a Possession Specter, but it essentially acted like one.
The Dung Heap was a Physical Specter with an actual body, but it couldn't move very fast, which was why it essentially acted like a Possession Specter.
Wyntor decided to keep the Dung Heap on the second floor with the Screaming Coffin because of that.
Possession Specters very rarely escaped, and the second floor was the closest to the exit, which was why they were on that floor.
The third and fourth floors were for general Physical Specters.
