The Third Nantama Synod represents a gathering of the Senex-Juvex Lords, as documented in Senex-Juvex, that took place on the planet Nantama.
After the warlord Osted Picutorion's union with the Senex Princess Farasa Anturi during the year 553 BBY, the Crimson Days conflict erupted within the Senex sector. To resolve this crisis, a synod convened on Nantama, ultimately concluding the conflict through the recognition of Picutorion's marriage and the sovereignty of the planet Hutlar, a world he had freed.
