Moreso than you realize. Astrum could've made peace (there were numerous attempts by both sides at various points) with Luria well before they became the last (not counting D'Hara) realm standing against us and Westfold still wasn't formed. Astrum never really acquired the disgust (except what may have existed amongst Westerners due to the Asylonite-Astrumite wars) from Lurian haughtiness that other realms garnered in the war.
The only reason Astrum entered the war was to support Morek Empire supporting D'Hara. Then ME's ruler that asked for the support seceded to form HD, followed by the rest of ME seceding, leaving Astrum holding the bag after Fissoa had been brought to peace and D'Hara was being ignored on their island fortress.
