Tanu was a Solodoe male who acted as the Chief of Security aboard the cruiser of Ambassador Ketas. During negotiations with the Plinovians on Station Zeta, the Jedi diplomat Arath Tarrex stole Ketas' seal of office, using the Force to make Tanu delete the security recordings and forget he had done so. After Ketas' accusation against the Plinovian ambassador caused him to self-combust, Tanu spoke with the Jedi Rael Averross, Dooku, and Qui-Gon Jinn, who discovered that the security chief was unable to remember investigating the recordings.
