First Mentioned: LIAB Prologue 13
Unatard is a small city of the Gobwin Knob side. It was one of the eleven cities Gobwin Knob controlled prior to the war against the RCC. It was recovered from Unaroyal during the counter attack launched following TBfGK. The city may have been captured from Unaroyal in the first place. It appears to be close to Hobbittm territory.
Real World References
"Unatard" seems suspiciously reminiscent of "unitard", which is a type of one piece leotard.
