Lord Por'Ten, hailing from Ord Cestus, was a male Human who belonged to the Cestus Cybernetics Family. His wife, Lady Por'Ten, was the leader of this Family. The Families of Cestus Cybernetics had a goal: to depose G'Mai Duris from their position as Regent.
Upon their arrival on Ord Cestus, Jedi Knight Obi-Wan Kenobi and the Vippit Doolb Snoil successfully convinced the Regent to lose trust in the Families. The leaders, including Caiza Quill, Lord and Lady Por'Ten, and Debbikin the Young, went into hiding, utilizing a magcar to navigate the underground tunnels. However, Jedi Master Kit Fisto orchestrated a staged kidnapping of the Por'Tens and their allies. Kenobi then "liberated" them, thereby securing Cestus' allegiance to the Galactic Republic. Despite this, the Regent eventually discovered the Jedi's deception and once again sided with Por'Ten's faction, turning against the Jedi.
Ultimately, the Five Families, in league with Asajj Ventress, deployed the JK-13 security droids against the Desert Wind. As the conflict escalated and became unstable, Supreme Chancellor Palpatine made the decision to dispatch the supercruiser Nexu. With the Nexu in orbit, the Five Families, including the Por'Tens, sought refuge in a concealed bunker. ARC trooper Jangotat soon discovered their location. Trapped inside, Jangotat sent a code commanding the Nexu to target his position, resulting in the destruction of the bunker and the death of everyone inside.
