Silood was a Rodian male aide who worked for Senator Onaconda Farr during the Clone Wars. He gave the eulogy at Farr's funeral, after Farr was murdered by another aide, Lolo Purs.
Silood, or at least his character model, was first seen in Ziro's Palace in the feature film that debuted the series on August 15, 2008. He was sitting next to the character model used for Pune Zignat. It would not be impossible for Silood to be present at this Coruscant establishment at the time, as Onaconda Farr was also in the area. He appears in another scene set in Palpatine's office.
