Primus

Primus is a kett second-in-command to the Archon and is trusted with leading many of the kett's most dangerous factions. She is a hands-on leader and orders from her are treated as coming from the Archon himself. Her main area of responsibility appears to be managing the exaltation and conquest of Heleus.

The Primus is believed to be extremely orthodox, ordering punishments for kett who deviate from social norms and traditions. She is also concerned over the missions to investigate Remnant technology since they intervene with military exercises and recon missions.Ryder can meet Primus on Elaaden, where she reveals herself "as a traitor" to the Archon. She believes that Archon's obsession with the Remnant derails their cause and incites chaos. Furthermore, she wants Archon gone and thinks his quest for Meridian is for his own ambition. It's possible to make a deal with her.

After the Archon is killed, Primus becomes de facto leader of the kett in Heleus Cluster.
