Boscha and Tibbles were invited to Luz's belated eighteenth birthday party, despite being her enemies. I doubt Terra Snapdragon, Adrian Graye Vernworth and Vitimir would've been invited since they're still evil and showed no remorse for their heinous actions. The same thing goes for Odalia Blight. I'm not sure about Mason, Hettie Cutburn and Osran, though. Warden Wrath seems to have redeemed himself off-screen, so he and his son Braxas could've gotten invited to Luz's belated eighteenth birthday party.
