Universal Church of Truth
The Universal Church of Truth was a massive alien religious cult that spanned many star systems across the Milky Way Galaxy. It was headquartered on Sirius X in the Hercules star cluster. The church was led by a being known as the Matriarch, who worshiped the Magus, which was the corporeal evil persona of Adam Warlock. Adam Warlock fought up against the Universal Church of Truth in the modern timeline. The Universal Church of Truth was responsible for a massacre on the planet Zen-Whoberi, which resulted in the deaths of nearly the entire Zen-Whoberian race. Gamora was its sole survivor.
