The Zerayd was a Galor-class warship built and commandeered out of spacedock in 2375 during the Dominion War by the combined Cardassian-Starfleet rebel group, the Thirteenth Order. The Zerayd has multiple Dominion upgrades in its defensive capabilities, to include upgraded sensors, transporters, shields, and structural reinforcements. Due to Dominion mistrust, however, its offensive weaponry remains standard Cardassian technology. (Star Trek: Sigils and Unions--The Thirteenth Order)
