Having Terran in the war gives Kabrinskia the excuse to pull in Astrum and the other SA realms into the fight. I honestly haven't seen a war where SA participated that did not involve gangbanging the enemy realm. See: Springdale vs Virovene, Morek; Thulsoma vs SA; Averoth vs SA; Caerwyn vs SA; Summerdale vs Libero, Morek.
