Dace Diath was a male Human and one of many Jedi Knights who trained under Master Vodo-Siosk Baas. He spent the majority of his early life on Tatooine being taught his initial training by his father, the Jedi Master Sidrona Diath. Upon completion of the training, he traveled to Ossus and became an apprentice to Master Vodo. He would eventually be one of the Jedi sent as reinforcements to help Ulic Qel-Droma during the Freedon Nadd Uprising on Onderon. He later participated in the Convocation at Mount Meru on Deneba and fought against the Krath during the Great Sith War.
