## Item description

This is the description text Roblox carries for the item, quoted verbatim:

> Cold as the steel that covers his towers walls. He doesn't know how long he's been in the depths of his tower nor if time has passed at all. When an Underkeeper becomes restless from their oath, they tend to do an assortment of odd things. This one likes reorganizing the furniture in every room two times a day, give or take.
