|Species:||Barn Owl (Tyto alba)|
|Appears in:||The Siege|
Uklah is a female Barn Owl, or Tyto alba. She was a former Pure One infiltrator. At that time she was known as Purity, a name she later described as "pure nonsense" after she was renamed Uklah by Skench and Spoorn.
Her number was 92-01 at St. Aegolius Academy for Orphaned Owls. She told Otulissa that she betrayed the Pure Ones, although Otulissa and Digger thought she was an infiltrator when Otulissa saw her slipping flecks to another Barn Owl. Uklah explained that she did it so the other Pure Ones wouldn't think she was a traitor. Her ultimate fate is unknown, for she is not mentioned in any other book after The Siege . It is possible she was discovered by the Pure Ones and murdered when other infiltrators learned about their double-crossers during a skirmish initiated by The Band.
