The A clan consisted of members of the Caamasi species and was the paternal lineage of New Republic Senator Elegos A'Kla. Elegos A'Kla's father, an A clan member, procreated with a female from the Kla clan, which led to A'Kla's birth. Consequently, A'Kla possessed the ability to readily transmit memnii, significant memories experienced by Caamasi that could be imparted to fellow Caamasi, to those within the A clan. During a conversation with a Human male called Corran Horn, A'Kla referenced his father's clan.
The initial reference to A occurred within I, Jedi, a novel penned by Michael A. Stackpole and initially released in 1998.
