Although not an in-universe source, Patrick Ness has clarified the spelling of Lorr here: https://twitter.com/Patrick_Ness/status/802934048645582848. Therefore, this location would become the Lorr homeworld.

The Lorr homeworld was a planet which was destroyed. (TV: The Metaphysical Engine, or What Quill Did)
