It was reported in the media on Alphard in September 3077 that couriers from the Circinus Federation border of the Hegemony were bringing news that a Marian offensive against the Federation had died effectively stillborn, with probing attacks on the planets of Thadora's Land and Zorn's Keep being rebuffed by significantly stronger Federation forces. The rumoured defeat was generally assumed to be evidence that the Federation was receiving large scale assistance from the Word of Blake.
