Hello,
Per TRO:3039, The Samurai line is listed as destroyed in 2774 during the Amaris Coup.
Per Dark Age: Republic Worlds (3130), p. 189, "Mizar World Profile" the world of Mizar was never attacked by Amaris troops because it had Lyran Troops on world and even Amaris wasn't dumb enough to trigger a war with another House while fighting the SLDF.
I'm wondering if the World info is incorrect or if maybe the year is wrong & it was destroyed post Coup in the 1st SW?
