The Blockhouse was a building on the planet Odryn which was used as a last refuge by the Feeorin during their warring days with the other villages. In 3963 BBY, fugitives Zayne Carrick and Marn Hierogryph were apprehended by the Feeorin after sneaking out of the Sanctum of the Exalted and were brought to the Blockhouse for interrogation.
