Loppurets: Their purpose

[Khalithar]

I assume they were created by the same Amaurotines who fashioned the structures on the moon to possibly to serve as helpers in the absence of fellow Ancients.

This was my interpretation as well.

Though I have a crazy theory that the Lops are Amaurotines that somehow managed to survive and since degenerated and/or evolved in to space bunnies.
