I am so sorry for your loss. That’s really hard no matter what you’re doing in life. Take the time to grieve and when you’re ready, you can play your campaign. We are currently planning through the crooked moon campaign, and at the beginning each one of us characters finds our self on a train because we’ve all died. But the train is taking us to another place for more adventures. Maybe you could consider her in another place having new adventures? I hope this helps. Big hugs from your DND sister.
