|Mergo's Wet Nurse|
It is a very simple arena, with only one way in and out, through an elevator that is directly in front of where Queen Yharnam lies in wait, gazing at it from below.
On the center of the arena stands a baby carriage, not unlike those found in the regular town of Yharnam, yet, still at the center, are dozens of bones, likely human, strewn across.
- The Wet Nurse's Lunarium lamp becomes available after defeating Mergo's Wet Nurse.
- It is the final area located in the Nightmare of Mensis.
