In the Original series, there were two notable moles: one called the Professor and the other one called Blink. Two more moles were revealed later in the series, who were both relatives to the Professor and Blink. In Spyro: Shadow Legacy, it is assumed that they inhabit a realm in the Forgotten Realms called Moleville.
The Legend of Spyro series
In The Legend of Spyro series, before Malefor's existence, the Moles have a long, time-honored alliance with all of Dragonkind, and to honor their friendship, they built the Dragon city of Warfang. Not only are they the architects of Warfang, they are also its protectors. What they lack in size is more than made up for in heart and courage.[1] They seem to be a highly-advanced race specializing in technology, as shown with their weaponry and machinery. The moles are also notable to have participated in the battle against Malefor's army in The Legend of Spyro: Dawn of the Dragon.
