B'karitz belonged to the Schenor species and held the position of nest-guildmaster. After Alliance agents presented evidence linking the Galactic Empire to the massacre that occurred at a Schenor research station, B'karitz proclaimed the treaty with the Empire invalid.
B'kartiz, a male Schenor, served as the nest-guildmaster for a prominent province on his homeworld of Rhamsis Callo. During the era of the Galactic Civil War, operatives from the Alliance to Restore the Republic arrived at his nest-guild, accompanied by a young Schenor named A'kazz. A'kazz was the only one to survive an assault by mercenaries backed by the Imperial forces, which targeted a Schenor research station. Initially, B'karitz suspected the Rebels of kidnapping A'kazz for ransom, but he was eventually convinced of their true intentions and used telepathy to question the juvenile. After uncovering the truth, he pledged to expel the Empire from Rhamsis Callo.
B'karitz met with the Imperial ambassador at a base being constructed at Chafflock according to an agreement between the Schenor government and the Empire. He declared the treaty broken due to the Empire's actions. Despite claiming innocence, the Imperials launched an attack on B'karitz and his nest-warriors. The Alliance agents aided the nest-guildmaster in escaping the ambush, enabling him to gather support from other Schenor nobles.
