The renowned Anzellan Droidsmiths, a trio of Anzellan droidsmiths from the planet Nevarro, had achieved legendary status. During the era of the New Republic, Din Djarin sought their expertise to repair IG-11, who had previously initiated his self-destruct mechanism. The Anzellans encountered a significant obstacle in their repair efforts: IG-11's memory circuit was damaged, and replacements were exceedingly scarce due to discontinued production. Despite this setback, the Anzellans persisted in their work with IG-11's remnants, ultimately reconstructing him into IG-12, a Mech designed for pilots of Anzellan-like size, including individuals such as Grogu.
