"After a bit of searching, I find an ostrich tied to a rope hiding in the middle of the layer."
– The Protagonist's narration in chapter 11, describing Salbey's first appearance.
Not much is known about this mysterious Ostrich. Some say that they created the OfficeTale universe. Others say that they are just a normal Ostrich. One thing is for sure, though: They seem to be sentient.
More will be revealed about them in the future.
